maybe i didn't get it but: why this is a physical card instead of an app on a smartphone? what's its advantage?
This was partly an instinctive decision, but I think it's too easy to go mobile. Part of the reasoning for having a tangible card is the novelty and the failproof factor behind it.

No advantage, but no disadvantage either.
