Electronic Cash Registers and Point-of-Sale Terminals

A selection of cash registers exemplifying their technological development from 1878 until 1970.

Some of these devices simply combined a printing electronic calculator with a cash drawer.  More elaborate registers not only tracked accumulated receipts, like a traditional cash register, but handled credit card transactions and allowed clerks to scan merchandise to read off prices. These, in turn, served as input for computer systems.
