This is potentially useful for the US market as chip/pin is very new to us and only recently rolled out via major banks this year (I literally just got my new Visa card with a chip). I can see how Europe is far ahead of the curve.

My initial questions/concerns are as follows:

Will this be usable in ATMs? I can't visibly tell if it's too wide to fit.

Is there any planned security functionality to lock the card via your paired mobile device? I'd like to be able to supply a password to unlock for a short period of time for usage.
