Scamables

By Adrian Lane

A post at PCI Guru got my attention this week, talking about a type of rebate service called Linkables. They essentially provide coupon discounts without physical coupons: you get money off your purchases for promotional items after you pay, rather than at the register. All you have to do is hand over your credit card. Really.

Linkables are savings offers that can be connected to your credit or debit card to deliver savings to you automatically after you shop. It’s a simple and convenient way to take advantage of advertisers’ online and offline promotions, with no coupons to clip and no paperwork after you shop. Offers can be used online and offline just by using your credit or debit card.

This idea is not really novel. Affinity groups have been providing coupons, cash, and price incentives for… well, forever. And Linkables is likely selling your transactional data, but with the added bonus of not having to pay major card brands or banks for the information. Good revenue if you can get it. But there is a big difference for consumer security when someone like Visa embeds this type of third party promotional application on a smart card – where Visa maintains control of your financial information – and handing out your credit card. I know we are supposed to be impressed that they have a “Level 1 PCI certification” – the kind of certification that is “good until reached for” – but the reality that is we have no idea how secure the data is. Sure, we hand over credit cards to online merchants all the time, but the law provides some consumer protection. Will that be true if a third party like Linkables suffers a breach? There won’t be any protection if they lose you debit card number and your account is plundered.

I would much rather hand over my password to a stranger for a candy bar than my credit card for 10 cents off dishwasher detergent, paid some time in the future. I can reset my password but I cannot reset stupid.
