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.




Based on Coin's FAQ:

1. Yes, it should be usable with ATMs without issue.

2. You cannot lock your coin with a password, but it will deactivate after it loses contact with a phone after a user-specified amount of time. In theory, I'd assume you can disable Bluetooth on your iPhone and it will effectively "lock" your Coin until it can pair with your device again.


Would be nice if there was a way to physically unlock it. I can imagine my phone dying – preventing me from making any kind of purchase.
