I look forward to the day the whole concept of getting pieces of paper from a machine in a wall is looked upon as a vaguely amusing aspect of the past.

ah so your the one fumbling with a credit card and holding every one up at the bar when I want to get a round in. Personally I like having access to cash reduces the attack surface for me when compared to handing over my card for every transaction and DONT! get me started on NFC credit cards that can be debited with NO interactinon

  > ah so your the one fumbling with a credit card and holding every one up at the bar when I want to get a round in. Here in Canada I just tap my card on the machine and walk away - much, much faster than trying to count out the right amount of cash, then waiting for change, etc. > and DONT! get me started on NFC credit cards that can be debited with NO interactinon Let me guess, you also didn't like when it was possible to make CC payments over the phone with no signature (!) And you also didn't like when it was possible to make CC payments over the web with no signature AND no actual human (!!!!!!) Things progress, get with the program.

    You do know the Chaos Club in berlin demoed a nfc harvester years ago walk through a crowd of unsuspecting commuters and take 5 pounds from everyone. BTW I have developed a Paperless direct debit system so I do know what the flip I am talking about.

      It's a risk, but you can fix it on the backend, away from the end-user. If they were bitcoins then sure you need interaction for NFC. But credit cards are a closed system on the merchant side, any new identity pulling only NFC traffic would be very suspicious. NFC would always be an expected proportion of overall captures. So it's simple to defend against this attack without killing the feature.
