DEBIT CARD: An increasing popular means of accessing the funds in a bank checking account. While debit cards look (and taste) almost exactly like credit cards, they are fundamentally different in how they are processed on a bank's end of the transaction.

This translates into a positively-sloped supply curve for profit-maximizing competitive firms.
