Death to NFC for payment.

 

I use NFC for payment. I think its wonderful.

From what I've read, NFC is lacking any valid security solution. I refuse to use it for payment and I refuse to hold any credit cards with an RFID chip.

 

Majik, NFC is secure. Data used is not even available to the device, this is because of something called Secure Element and Trust Zone. As far as you're concerned the data is encrypted and the biggest security concern you should have is that the Trust Zone uses a hardware initiated chain of trust.. Galaxy does and refuses to boot without it... I've successfully broken chains of trust but secure element doesn't work after that.



. Replay attacks are also not effective.

Honestly, I haven't looked at it in the past year, but I recall Man-in-the-middle attacks and eavesdropping being valid concerns for mobile devices and NFC (eavesdropping more so than M-i-t-M obviously).
