Fingerprints Replace Credit Cards in Seattle
prostoalex writes "According to CNET News.com, Thriftway introduced biometric systems in its Seattle stores as far back as 2002. The customer would have to be identified first and submit his own fingerprints, as well as register credit cards with the grocery store. But then a Pay By Touch system became quite popular among the store regulars. According to CNET, "one man even drove 400 miles to use the technology". The store also reports 0% of such transactions being fraudulent."
If someone gets an electronic imprint of your credit card number, you call VISA and get a new number.
If someone gets an electronic imprint of your finger print, you'll be chasing down fraudulent purchases FOR THE REST OF YOUR LIFE because you CAN'T change your finger print.
Ticketmaster, 5 years later, "I'm sorry sir, but you *DID* buy 10 first-row superbowl tickets. Our computer says you did it over the internet and we have your finger-print scan on file to prove it."
RUN, don't walk, when someone in a store asks for a scan of your finger-print.

People don't realize just how *dangerous* the fraud would be if this became widespread.
Take into account that we touch a LOT of things. Daily. You know those seedy, scammy ATM's? Wouldn't be very difficult to make one with a thumb reader to conceal an instant CCD-based scanner or something of the sort. All the machines check for is the pattern, and it would NOT be hard to fake this.
Rubber thumb overlay, anyone? The HEIGHT WOULD NOT MATTER, the machine would detect the right print no matter how long the grooves were. Sure, it won't work at a store, but it WILL work at an ATM.
But here's the worst part.
Once your print has been *breached*, you simply *can't get another one*. You're screwed.
Yes, safeguards can be put to minimize the use of overlays, but once again, only in official locations. Independently owned ATM's either won't ever be able to use this technology or will ruin it the very moment those prints are made public.
It would NOT be hard to rapidly prototype a piece of rubber (or some other, better, squishing polymer) based on a figureprint picture, let alone streamline the process to make dozens or even thousands more.
Of course, if it was purely for stores (and stay wary of those self-checkouts), maybe.... maybe.
I dunno, maybe I'm off my rocker here, I just came up with this counterargument instantly. The thought of someone with lots of stealing in mind coming up with a way to fake prints to use in unmanned scanner locations (let alone someone forcing someone else's thumb onto the scanner in a much scarrier mugging incident) is kind of scary.
Wait a second now...
Perhaps a bioelectric scanner that doesn't work (has to be tested with a variety of conductive materials, constantly, along with calluses...) unless a real live thumb is touching it still leaves you in danger of mugging (and setting it up so that the customer can't purchase unless they're calm would only lead to MUCH scarrier mugging incidents) but would stop fraud for the most part.
Yeah, still a long way to go before widespread use.
