Banks Find Way To Sell Consumers' Shopping Data

nonprofiteer writes "Banks plan to compete with Groupon and LivingSocial by targeting coupons and deals at credit card holders based on their shopping habits. They found a way to do it without violating financial privacy laws: 'They're "selling" shopping habits the same way Facebook "sells" personal data about its users: in-network. It's a clever privacy work-around. Just as Facebook allows advertisers to specifically target certain kinds of users based on their profile information (without actually providing that profile information to the advertisers), banks plan to allow advertisers to send deals and coupons to their customers based on what they've bought before. That way, no user data actually leaves the network — instead, deals just enter the network. Each time a customer cashes in on one of those deals, the bank gets a commission.'"

    So, I send a bank a deal aimed at consumers who (for example) bought alcohol and restrict the geography to an overwhelmingly Mormon neighborhood and get back a list of names. I cross reference those with church memberships. I now can target the backsliders.

      You missed the point, but still have the right argument.

      When you pay the bank, you don't get back a list of names at all. The bank would be sending out junk mail, SMS, or email based on your chosen demographics. It would be a 3rd party offer.

      Most websites, companies, etc. allow you to specify that you don't want to receive it, but they also specify that affiliates and subsidiaries get access to to the data. The banks don't get that loophole in this case.

      In your example, what you are really pointing out is that whatever percentage of customers click on the links, or even view the email with downloaded pictures, are revealing themselves and losing their privacy. In order for the bank to receive a commission it needs to admit that particular customer was indeed part of the chosen demographics.

      It violates customer's privacy in spirit, in actuality the customer is mislead at best, and worst responsible for losing their own privacy through their own actions.

      In other words, the customers are being tricked into confirming purchasing habits outside of the bank.

      Very dirty and hopefully there will be an opt-out option for this voluntarily, or by law.

      This isn't the whole story.

      Your bank only knows that you spent money at Nordstrom. It doesn't have an item level transaction history, so it cannot know that you bought shoes unless it has access to Nordstrom's transaction logs. Therefore, for this to really fly, the retailer has to share their t-logs with the bank. So the banks aggregate t-log data from a number of retailers, and then resell that information back to the retailers.

    I place a certain value on my privacy. I had one of those "loyalty cards" years ago at the nearby grocery. I'd use it to get the cheaper price on the stuff they sold me. In return I got a bunch of junk in the mail trying to sell me more stuff. When I stopped using the card I got less junk in the mail.

    I had a credit card. In exchange for using the credit card the credit card company sent me stuff in the mail trying to sell me more stuff. They would also call me at home. How far and wide this information on my buying habits went hit me when I used my credit card at a gas station I don't normally visit and a couple weeks later I got a credit card advertisement in the mail from the gas station. I pay for my fuel and groceries with cash now excepting rare occasions when I forget to stop by the bank before my wallet gets too thin, then I pull out my debit card.

    Not only does using cash prevent banks from selling my buying habits it also avoids the threat of my bank account information from being stolen with those hidden card readers that are popping up on gas pumps and the like. I don't even like to use ATMs any more. Not only is there a threat of my card getting copied by a hidden card reader the ATMs spit out only $20 bills. With a tank of gas costing over $60 and a grocery cart filled with food typically costing around $100 I prefer to see a real live teller so I can get $50 and $100 bills, that way my wallet doesn't get so fat and I can still buy what I need.

    Now, I just wish those vending machines would take $2 and $5 bills. With a bottle of soda costing around $1.50 it makes sense to me to take the larger bills. This is also because I've had to not buy a drink because my wallet is full of $5, $20, and $100 bills.

    All the crap in the mail, and the phone calls interrupting my supper, stopped for the most part once I got rid of my credit cards. Not using a debit or credit card for most purchases does mean a few more trips to the bank and having to pay for gas inside the station but that is a minor inconvenience. The bank is within walking distance of my house, and I'll often go into the gas station anyway when I travel to get a snack or use the restroom. It keeps the junk mail and cold calls down.

      I have to admit that I use my credit card for pretty much everything, they pay me a cash dividend, and as I always pay my balance in full on the due date, they never charge me a penny of interest or other fees. It's convenient, and it saves me money.

      I have received a total of 2 phone calls from the credit card company since signing up for the card 10 years ago. The first was them trying to sell me on a "premium" card with yearly fees. I declined and asked to stop receiving such offers. I've never been called for one again. The second was their fraud department, and they had legitimately flagged a purchase I didn't make, they refunded the purchase, cancelled my card, and couriered me a new one right away.

      I have received 7 pieces of mail from the credit card company since signing up, 4 included new cards (initial card, replacement for the fraud case, replacement for expiry, "upgrade" to chip) the other 3 were offers to increase my credit limit (with no catch other than the responsibility that comes with being able to borrow larger amounts of money at a time)

      I have never received a single ad by phone, mail, or email, that I have any reason to suspect has had anything at all to do with my credit card usage. The most I have ever had was the small box at the bottom of my monthly bill suggesting I upgrade to one of their "premium" cards with yearly fees, it's unobtrusive, and it's from the credit card company themselves, I always decline.

      Same here. But the banks have fought back. Banks are not open anymore outside office hours, so I have the choice to either take a day off to get my money or to use an ATM. Where I live, you cannot even bring cash to a bank anymore. You read that right: banks don't accept cash. Banks' terms of service include sections on how you MUST cooperate into investigations about where your money is from. And our government made a bank account compulsory for the payment of salaries.

      Unless you pay with cash every single time using fake info on the loyalty card won't help you, they will record your real info from your checking/debit/credit card and cross-reference it for all past and future purchases. Even playing "musical loyalty cards" with a bunch of other people doesn't help too much unless you swap cards frequently.

    5) Customer uses coupon

    Now, we are giving information to the advertiser about the customer. This is BAD, and possibly illegal.

    Note on the one hand that it was the customer's action that led to the information leak.
    Note on the other hand, however, that the customer does not know what information was to be leaked, and so cannot be said to have given consent. Consider if Macy's asks that a normal-seeming coupon be sent to people who shopped at kinkysextoys.com, using that coupon is in no way tied in the mind of the recipient to the information at stake.

    So that's the problem. The solution? Include the relevant information with the coupon. That way, the customer knows what information they are giving to the advertiser, and can absolutely be said to be opting in at that point. This does run some risk of others reading the coupon, and so these coupons must therefore be treated with the same respect given to any other form of transaction history until the customer decides to disclose them publicly by using the coupon.
