This doesn't even read as sexy-futuristic for the sake of sexy-futuristic. Every major city metro with a contactless farecard does a better job of making it seamless and futuristic.

From a security standpoint, biometrics are ugly. You've gotta put a large fudge factor in everything to accomodate natural inconsistencies. Nobody wants to see "come back and try to purchase after the blister heals". But that means there's a wide range to build mocks that fool the scanner. And, of course, once the biometric signature is leaked, you can't exactly change it on your next login.

In a way, the obsession with biometric payment feels dystopic. I wonder if the real dystopic angle is that biometrics undermine "consumer spoofing". Tying every transaction to a physical body, rather than a card number, probably exposes new profiling data at the sub-household level.
