online payments and credit cards: I have questions

As I make the rounds doing year-end donations, I'm reminded of two things that have long puzzled me:

  1. Some web sites auto-detect the type of credit card based on the number. Apparently all credit-card numbers that begin with "4" are Visa. (I don't know if the reverse is true: do all Visa numbers start with 4?) Being me, I've cycled through the other nine digits and nothing else produces a match based on a single digit. What are the patterns for other providers? And are all these sites using some standard library for this, or are programmers really coding that by hand?

  2. Years ago, a three-digit code ("CCV") was added to cards to mitigate fraud. On a physical credit card, this number is stamped rather than embossed, so those old-style manual credit-card gadgets that took an imprint of your card (on actual paper, with a carbon!) couldn't record it. Um, that's fine I guess, but online, that number isn't any more secure than the card number itself. And someone who steals your physical card has the number; it's not a password. Does that number have another purpose?

Oh, Credit Karma, who writes your copy (or programs your algorithms)?

Your hard work this year has really paid off, and we want to remind you how far you've come.

(Um, I have? Also, this sure sounds like "you were having trouble and you're better now, attagirl!. I feel patronized.)

About a year ago your TransUnion score was X.

Check in now to see your updated (and uplifted) score, and keep up the awesome work.

"X" sounds about right, actually. Curious, I took a look. Why yes, my score has gone up! It is now X+1.

Uh, thanks?

(Fluctuations of a few points are completely normal. I expect to take a slight ding this month because we paid for something substantial online with the joint credit card. It'll come back next month when we pay that bill. You can't always write a check, but any use of your credit card affects your score at least a little.)

Trolling Wall Street

This is oddly fascinating, even though I don't understand all of it. If I understand correctly:

A "short" is a bet that a stock price will fall: you promise to sell it on a certain date at a certain price, but you don't actually own the shares. On that day, the idea goes, you'll buy the shares at the lower price you expect and then turn around and fulfill your contract, pocketing the difference. I don't know if regular folks like you and me can do that, or if only investment funds and professional stock-market people can. There are some rules that are different for the big players and the little folks; I don't know if this is one of them.

So... some big Wall Street hedge funds (one often mentioned is Melvin Capital) placed vast quantities of shorts on a gaming-gear company that isn't doing well (GameStop). A bunch of people on Reddit observed this and said to Wall Street: hold my beer.

They bought the stock. Hundreds of thousands of people on Reddit bought the stock. At that scale, any individual participant doesn't have to buy a lot; you could play this game for $20 back when it started. And it's not like you can spend that $20 going out to a movie right now, so there was probably an untapped market of bored people looking for fun.

Did I mention that this subreddit bills itself as "like 4Chan for investers"? And did I mention that Elon Musk tweeted about it to his 42 million followers? That subreddit has way more than "hundreds of thousands" of subscribers now.

What happens when lots of shares of a stock start getting bought? The price goes up. The price for GameStop shot up from less than $20 to, at one point, $347. And I think it was higher; I was only able to find daily closing prices, and the hour-by-hour swings have reportedly been wild. There's some background information on CNet.

The stock price, of course, won't stay high. It's a ridiculous price for that company, and eventually the market will bring it back down. But in the meantime, those hedge funds holding shorts have lost billions of dollars -- remember, they still have to buy the stock on "short day", at whatever price is then current, and then sell it for $10 or whatever the bet was.

The Redditors and crew, meanwhile, have turned their sights to other stocks; Blackberry and AMC have been mentioned as other companies in trouble that investors have considered prime candidates for shorts. Stock exchanges and Robinhood have stopped trading at times or restricted purchases.

By the way, the people rallying against Wall Street have a song -- a sea shanty:

I don't know what a "tendieman" is (Google has been unhelpful), though I assume it has to do with tendering, in this case selling at the right time. Ryan Cohen is a major investor in GameStop who's recently been investing more and trying to change the company's business strategy, though I can't tell if he has an actual position there. (The song implies he's on the board.)

As far as I know, the people organizing on Reddit and wherever else aren't doing anything illegal. They're not insider traders with privileged information -- quite the opposite. They're just...massively trolling big investors who traditionally make a lot of money with these kinds of bets. Some of them seem to be in it for the laughs; some are trying to make money riding this (but a lot of them will probably lose money, including anybody who tries to join in now). The line between a movement and a mob can be fuzzy; I'm not sure which this is. I wonder what the other damages are going to be. They're pitching this as little people versus big investors, but will little people with modest retirement funds end up taking some of that damage in those funds too? Or are hedge funds more esoteric and not usually part of IRAs and suchlike?

Bizarre, fascinating, and unsettling.

small payments are still hard

If you use Patreon, a site that connects creators (writers, artists, musicians, cartoonists, anybody) with people who'd like to support their work, then you probably already know that they're about to start charging the patrons (funders) for the credit-card transaction fees. (So you signed up to pay somebody, say, $1/month, and you'll now be charged $1.38.) What you might not have noticed is that they're charging a little more than what the credit-card companies charge them, and they're charging for each individual transaction even though they charge your card once for all the creators you support each month. Uh huh. [personal profile] siderea did some money math on their current practices.

One of the complications in trying to do online financial match-making, whether that's Patreon or PayPal or others, is that actually holding money is messy, legally speaking. So creators who have income and support other creators don't get to pay from their income (which is just bookkeeping); each transaction has to start with a credit card and end with a deposit. Or so it sounds.

Back in 1995 when the web was still young, I went to work for a micro-payment research project at CMU, NetBill. The idea was that consumers used a credit card to load some small amount, like $20, into a NetBill wallet, and merchants could sell digital goods for a nickle or a dime or $1/month or however they wanted to structure things. There was a secure protocol with escrow so nobody got screwed, and nobody was paying transaction fees on ten-cent sales. Since this was a university research project it was never set loose in the wild, so nobody ever had to decide what NetBill's fees would be. What made me think back to that now is that I have no idea how the financial regulatory stuff was supposed to work; we were holding money, after all. What I do know is that the project had Visa and a major bank on-board from the start to make sure it would be legal. Now I wonder how they planned to do that. I assume the rules have changed since then anyway, but I now realize that this was a part of the business model that I had no real insight into.

(I joined the project in part because it sounded interesting and in part because it sounded like something that could launch a start-up and that sounded interesting. Instead, two years after I joined, CyberCash licensed the technology and that was the end of that.)

Making small payments was hard then and it hasn't gotten much easier since. If you want to publish through Amazon Kindle or iTunes you can still make some income that way (and of course the platform takes a large cut), but self-publishing for small amounts is still hard. And supporting people without going through the "make a sellable thing on Amazon or iTunes" is even harder.

Edited to add: Some donation-processing systems give donors the option to pay the transaction fees. For example, Jewcer, the site we used to raise funds for "Days of Awe - Mi Yodeya" a couple years ago, was like that, and most donors tacked on the fees. My congregation asks members to kick in the fees when we make credit-card payments and, again, it's optional. Sometimes I do, sometimes I don't -- depends on what the payment is for. But the key is that it's optional. If Patreon had offered patrons the choice instead of imposing the change, this might have gone over better -- but they couldn't do that, because they're using this to overcharge for those fees so people who know that won't go along with it.

Me: attempts to book tour in a different city.
Booking site: couldn't get approval.
Me: tries a different tour (and different vendor).
Booking site: nope, we don't like your credit card either.
Husband: tries (joint card) and fails.

Phone rings.

Caller: Hi, this is (bank).
Me: Oh good; I was just about to call you.
Caller: There were these transactions...
Me: Yes that was me.
Caller: Ok, better safe than sorry. We'll unblock your card now.
Me: By the way, here are some travel dates and locations.
Caller: Got it.

I'll gladly accept those five minutes of inconvenience for that level of fraud protection. I even still had a valid session for the failed transaction, so retrying was easy.

I would have called them with the dates and locations closer to the trip to avoid card declines, but I didn't think about how the advance charges would look.

charity fundraising

Dear Charities1 That I Already Support,

I sent you a sizable donation this year. Recently, even, because I mostly do that at year-end when I know where the annual finances ended up. You acknowledged receipt.

So stop bombarding me with email asking for donations, will you? If I weren't inclined to support you the repeated appeals would not change that -- in fact they would drive me away, as they've done with some of your predecessors. And even though I am inclined -- I like you and support you, after all -- I'm starting to weary of this. It feels like the left hand doesn't know what the right hand is doing. Get your fundraising people in sync with your receipts people, please. I want to support you, but your methods are growing frustrating.

1 Yes, the use of the plural is correct. I have gotten several email requests this week from each of two organizations I have a long record of supporting with single, annual donations.

weird economics

My employer provides free drinks, including soft drinks, but because ours is a small office we have to do our own buying. When supplies get low somebody goes to the store, which requires carrying cases of pop a couple blocks. Particularly during the winter this sometimes broke down, so that got us to look at options.

It feels wrong that it is cost-effective to buy our drinks from Amazon. That really shouldn't work. It can be less expensive to buy locally if there's a sale, but otherwise it's a wash -- and an Amazon box comes to our door.

Huh, weird.

how does your congregation raise money?

I'm interested in answers from all religions/denominations. (Please identify which you're talking about.)

I grew up going to a Roman Catholic church. Collection baskets were passed at Sunday services -- once for the church and, often, a second time for a special purpose (ranging from helping $disaster victims to buying a pipe organ). Members of the congregation were issued envelopes with an identifying number (not name) on the outside, so you could put cash in and still get a tax receipt at the end of the year. Children in religious school were also issued (small) envelopes; they were also numbered and I assume our coins were tallied with our parents' envelopes, but I never asked. Of course, some people (like visitors) just put cash directly into the basket, too.

This always struck me as dicey; how could an organization with regular expenses like heat and salaries and a building manage finances that way, other than by assuming that this year will be like last year? It occurs to me now that there might have also been a pledge system that I, as a child, never saw, but I'm just guessing here.

One of the things I found really refreshing about synagogues is that they have dues. When I found out about this I did a little happy-dance. Yay, no more guesswork! Join the congregation, get a bill, pay it, and everything's good. Right? (Aside: we couldn't pass a basket at Shabbat services even if we wanted to, because doing business and handling money are forbidden on Shabbat.)

Now that I've been part of congregational life for a while, though, I've realized that that's not the end of it by far. There are still special appeals, of course (we help $disaster victims too, after all), but there are also endowment campaigns, special appeals to supplement dues, fancy fund-raising dinners (with ad books, to draw contributions from non-members/businesses), and a myriad of other fund-raising activities. (I know that some congregations have a building fund with its own rules for member payments; we don't, so I don't really know how this works.) There are also fees for certain activities; the biggie here is religious school, which is a separate payment on top of dues.

My congregation -- and I assume this is true pretty much everywhere -- never turns anybody away for lack of ability to pay dues. We'll negotiate a reduced rate, sometimes quite nominal. Some of the other fund-raising is specifically to offset that. A draw from the endowment each year also offsets some expenses. I don't know if the proportion of our expenses paid for by dues is public information so I won't say, but we try to reduce that proportion by building the endowment -- through fund-raising, of course.

All of this makes me wonder when we risk hitting the point of "fund-raising fatigue" for members (I didn't grow up with this as normal so my perspective is unreliable), and what the mix of dues to fund-raising tends to be like elsewhere, and what other (fiscally-responsible) approaches are out there. What do others do? Are synagogues unique in having dues, or do churches have that too (perhaps packaged differently)? If you're a member of a church, does someone sit down with you and say "we expect you to donate $X this year"?

So, readers who belong to congregations of any sort, how do your congregations pay for expenses?

the phishers are getting bold (a cautionary tale)

I got a surprisingly-slick call this weekend. The caller said he was from my credit-card company (which he named) and proceeded to offer me a deal intended for people who don't do math. I interrupted him to say no. He kept talking and used the phrase "opt-out", implying that this unrequested service (with accompanying monthly fee) was going to start unless I took steps. That sure didn't sound like my credit-card company, which has treated me well for something over 15 years. I interrupted him again and played along:

Me: Ok, what do I need to do to opt out?
Him: I just need your city of birth.
Me: Whatever for?
Him: To verify that you're the account holder.
Me: You called me; don't you know who you called?
Him: I'm sorry, I need that to continue.
Me: I understand. It's important to protect customers from identity theft. Speaking of which, what's my mother's maiden name?
Him: Oh, I'm not allowed to reveal confidential information to strangers.
Me: You called me, remember?
Him: (babble)
Me: Ok. Topeka.
Him: Thank you. You've been opted out.

(No, I was not born in Topeka, nor have I used that response for any account.)

After I hung up on him I called my credit-card company. They do offer such an insurance plan (through a third party), but I was not scheduled to be called. I said I couldn't remember -- do they use my city of birth for a challenge question? No, they don't. The rep gave me the phone number of the company they use (which doesn't answer the phone on weekends), so tomorrow I will attempt to find out what they know about this. (Either they have an employee who stepped way out of bounds or it wasn't them.) Meanwhile, my company says they have noted that I declined this offer and if anything shows up on my account it will be squashed. Is there any place else I should report this? I don't have caller ID so we can't track the caller, but I'd kind of like to record somewhere that if someone tries to use my name plus a birth city of Topeka to open an account, it's fraud.

By the way, at no point in the conversation with the caller was my credit-card number mentioned. Hmm. (My company offered to change my card number, but that's a big hassle because of automated payments and they advised waiting to see if any suspicious charges show up. I am already in the habit of reading my statement carefully, so we'll catch it.)

I'm a little creeped out by this. It would have been pretty easy to be fooled, I think -- you can't "read back" on phone calls the way you can on suspicious email and the call went on for a while, so it would have been easy, I think, for people not especially fluent in phishing schemes to forget that credentials had not been established. This is not the Nigeria-style scam that plays on the stupidly greedy; this one could easily catch smart people who just aren't up on this stuff, I think.

I used to occasionally have a problem with an overnight power outage killing the alarm clock and causing me to oversleep, but I've more recently realized that having a UPS or three means never having to fear that again. :-) (Fortunately, today's power outage came after we were up, not in the middle of the night, and only lasted about five minutes.

allocating charitable contributions

This Shabbat we had a guest, Ruth Messinger from American World Jewish Service. She spoke Friday night about global communities and led a study session Shabbat morning on the theme of "to whom am I responsible?". We talked about communities and how they overlap and how this can influence our degrees of connection, and we talked in passing about how we make decisions about tzedakah (charitable contributions, though that's not a precise translation).

Read more... )

Ruth told us about an interesting family tradition she'd heard somewhere: when each kid in the extended family reaches a certain age (I think she said 9 in this case), a family member with the means sits that kid down for a talk that goes something like this: "Here is a check for $100. It's made out to your parents 'cause they have the checking account, but at any time during the coming year, you can direct them to write a check to any charity you like until this money is gone. If you come back in a year and tell me how you spent it, you'll get more to distribute next year." There is no request up front to justify the decisions but, she said, it comes out in the followup conversation. I think this is a neat idea; think of it as a teeny tiny foundation that gets people thinking about decisions and decision-making from an early age.

Maritan Headsets (from Joel on Software) is a long but worthwhile article on software standards -- both not having them early enough, and having them and trying to enforce them. Parts of it made me laugh out loud, like the paragraph containing this passage: "[...] but of course when you plug the headphones into FireQx 3.0 lo and behold they explode in your hands because of a slight misunderstanding about some obscure thing in the spec which nobody really understands called hasLayout, and everybody understands that when it's raining the hasLayout property is true and the voltage is supposed to increase to support the windshield-wiper feature, but there seems to be some debate over whether hail and snow are rain for the purposes of hasLayout..."

Rescue me: a fed bailout crosses a line seems (to this non-expert) like a good analysis of what just happened to the market and the dollar. (Need a login ID? Try BugMeNot.) I am more scared, and more angry, about our government's economic policies than I've been in a while. As someone on my subscription list said (I forget who), the people who actually took personal responsibility and saved rather than spending recklessly are the ones who are going to get hammered by this, while the idiots who bought houses (or corporate holdings) they couldn't afford and racked up tons of debt will be bailed out because we can't stand to say "too bad you were an idiot".

short takes

Words that are often misused #1: "periodic". To be meaningful, this word needs to be accompanied by some indication of the period. "Daily" is "periodic", but probably not what is meant in a recipe's direction to "stir periodically". :-)

Two facts that seem to be at odds with each other: (1) a lot of medieval Islamic recipes call for vinegar; and (2) Islam forbids the consumption of wine.

Our baron (who lives in a castle) shared one way to get your castle past the zoning board. I wonder how that's going to work out for the owners in the end, now that the neighbors have noticed. (Who would have thought you could build a castle on the sly in a populated area?)

Two interesting posts that showed up on my reading list within a few hours of each other, serendipitously: whom do you friend? (from [livejournal.com profile] cahwyguy) and who owns the conversation? (from [livejournal.com profile] jducoeur). Both have lots of comments that I haven't yet digested.

Words that are often misused #2: "rebate". A rebate is a refund of monies paid. If you give money to someone who didn't pay any (or as much as is being given out), the correct word is "gift" (or "grant", if you want to be more governmental about it). Just sayin'.

Query: can anyone reading this point me to a neutral high-level discussion of economics, that I can consume in an hour, that explains how merely pushing small amounts of money into the economy helps fend off a recession? What does the mere act of one-time spending accomplish, and does it matter whether it's splurge-buying or spending you would have done anyway? My knowledge of macro-economics is, as you can tell, a little on the spotty side. I don't care enough to read a tome, but I'd like to read something shorter, particularly if it doesn't come with an agenda. And yes, I realize that the rhetoric and the real reasons behind the stimulus package probably differ; I'm exploring the stated reason here.

My mother-in-law's seder has some singing, but mostly in Yiddish. This year (finally) I seem to have earned enough points with the family; I asked if we could add some Hebrew songs, offering to do the work (compiling and copying), and she said (via Dani) to bring a few. Yay. I'm going to make one double-sided sheet (including sheet music for some), on the theory that there's no sense wasting paper and this way there's a choice. Tiny steps... (At this seder I enjoy spending time with the people and I dislike the haggadah. At my father-in-law's seder, the haggadah is fine but the people aren't interested in doing most of it.)

At work we're about to get some expansion space, and they just published the new seating chart. People were given the option to stay put or take their chances. One of our neighborhoods (oh, did I mention that we have designated neighborhoods? that turns out to be fun, actually) is unpopular due to the way the space is set up. Every person there save one moved out. No one moved in. So the seating chart shows Beth amidst a sea of numbered spaces. There was some talk today of renaming the neighborhood; an early proposal was something like "Beth's Fiefdom" but I suspect that the latest will stick: "Bethlehem". If it weren't so close to Pesach I'd bring her a loaf of bread. :-) ("Bethlehem" is an anglicization of "Beit Lechem", which is literally "house of bread".)

San Francisco is about to ban plastic bags from grocery stores, saying that this will cut down on 1400 tons annually sent to landfills. I wonder how they came up with that figure. Do they catalog the landfills? Are they simply assuming that all bags produced go to landfills and wouldn't otherwise? Have they considered that some of those bags are recycled and, when not available freely, will just be replaced by other plastic bags in landfills? For example, I use them when scooping out the litter box, dog owners use them for a similar purpose on walks, and I know people who use them in bathroom trash cans instead of buying small bags for that purpose. I am not (in this entry) arguing against the policy; I'm merely questioning their data analysis. How do they know how much, if any, reduction there will be in landfills?

This article on Roth IRAs (link from [livejournal.com profile] patrissimo) seems to suggest that a simple money-laundering exercise lets one bypass the restrictions on using Roth IRAs. How odd. If that's true, it would be a way for people in higher income brackets to hedge their bets, which seems counter to the intent of the Roth. (Traditional IRAs are tax-free on the way in and subject to income tax on the way out, which makes sense if you think you'll be in a lower tax bracket when you retire. If you don't trust that tax rates won't go up, though, a Roth IRA is insurance -- you pay the income tax on the way in and nothing when it comes out.)

Yesterday I got a statement from my credit-card company. It was a transaction summary for 2005; I've never seen this sort of thing before. The front page informed me that last year I spent $X on food, $Y on entertainment, $Z on professional services, and so on for about 15 broad categories. That's the sort of thing that could be useful if you don't think about it -- but I'm the kind of person who thinks about it.

I'm not sure which possibility is more disturbing: that they are making inferences based on who the payee is (Giant Eagle sounds like groceries, etc), or that the merchants are providing the credit-card companies with categories for the transactions.

My record-keeping is not thorough enough for me to figure out which is more likely on my own. Perhaps I will ask them.

When I use a credit card I fully expect that the particulars of the transaction -- date, amount, and merchant -- are not private and might be mined. If it's really important to me, I pay cash. But I do not expect a description, even a high-level one, of the goods or services purchased to be part of that record.
