Jan 2012, Graeme Wall remarked:
paywave credit cards. Although I always feel a bit awkward using a
credit card for such small purchases.

Why? I usually have a rule that if I can pay by card I do.

Because I know all the processing and billing costs have to be paid by
someone, and in the end it's the consumers.

Handling cash has quite a high cost as well, again, ultimately paid by
the consumers.

As a rule of thumb it's about 1% for cash and 2% for credit cards.
