If I can by a coffee at Starbucks by waving a CPC, and it ends up on my

overnight once I've also registered a touch-out. But clearly it's all a
lot more complicated than that, given the kerfuffle to get it all in
place.

I wonder how they (or the bank) deals with a card that accesses an account
with nothing in it and no overdraft allowed. Does the bank have some sort
of "special" overdraft for that or do they just refuse payment and the
vendor is out of pocket as can happen with credit cards?
