[QUOTE=debro;2571802]What’s the range on these things?
Is it now possible to get an NFC reader, stick it in your pocket, then attend a concert, or other crowded place, and just charge everyone you walk past with phantom purchases?[/QUOTE]
or rake payment info from the device and sell it on the black market. They sell RFID readers that can scan hotel keycards so someone can make copies. I remember seeing a vid on youtube from one of the DEFCON conventions where guys were making them out of scraps and breadboards. I think there was a video about the Mastercard paypass system where a reporter had an actual POS cardreader in their pocket with a notebook and showed people how easy it was to scan their credit card number with it still in their wallets.
I don’t think i would sign up for this. It’s too easy already for crooks to steal your info. No need to make it any easier.
