Is there a credit card out there that is "developer friendly"? Like, can I use an API to create temporary credit numbers, push messages to an endpoint when new charges are posted, etc. I am looking for a credit card that allows me to automate my life.
Very interesting idea though I think that would be hard to do since there are a limited number of 16 digit numbers and if people could use a program to generate an infinite number (say, one for each transaction that is temporary so it can never be stolen) we would run out.<p>However, I do think that some combination of "paying by email" and some email programming could get you something interesting.<p>In any case, this idea should get more people thinking about the possibilities.
I think Bank of America has an online service like this. My friend pays for everything online with single-use credit card numbers with a limit exactly equal to what he's buying.
