NatWest to trial biometric credit card
NatWest is to begin a three-month trial of biometric fingerprint credit cards with 150 customers. The biometric credit cards will offer contactless payments using fingerprint verification for transactions
At the outset, it seems innovative and interesting. I extend my best-wishes to the Natwest team for this new initiative. However, I'm very curious for some details.
Can someone who understands this better, clarify a few points from a technology/feasibility point of view?
1. These cards are not really cards, are they? Won't they be needing a sensor, firmware, memory, computing power and some battery built into them? If yes, it becomes a mini-gadget in itself, not just a Simple-Card.
2. I am assuming that the fingerprint-verification is done at the card and not relayed to the server for a validation.How would one update (or program) his fingerprint into the card? Correct me, if I am missing something.
3. Couldn't this use-case be built into the Mobile App? Isnt it easier to exploit the inbuilt-sensors instead of duplicating resources?
