Visa To Push Swipeless Credit Cards

BobPaul wrote in to mention an initiative by Visa to allow for swipeless credit card transactions. From the article: "...consumers need only wave credit and debit cards within a few inches of a reader to complete a purchase. And for purchases of less than $25, no signature is required...Each transmission between card and reader has a unique code that cannot be reused even if it is intercepted". Update: 02/25 16:06 GMT by Z : References to RFID technology removed.

    Hey, Visa, if you think your RFID system is so secure, publish all the nice technical details on how it works, so we can be confident of its security. Otherwise I'm going to take my low-tech X-Acto knife and cut that RFID tag right out of the card. Considering that anybody can hack an RFID tag now, I'm not particularly inclined to trust this thing.

    Especially since it would be easy enough to wave an RFID reader at people's purses, back pockets, etc. At, say, $24 each, in a large crowd, you could amass quite a bit of money, and many people would never know it happened.

      *Here, "a distance" could be a few feet, or could be across a street through a shop window using a shotgun antenna (see bluetooth example).

Asking for photo ID sort of gets at what you are, though it can be forged by an ambitious criminal. But it could slow down the smaller thefts were it actually used. A pin code is actually useful IMO because it is something you know but is not used (for cost reasons mostly) for credit cards here in the US.
