Cash register
A cash register, sometimes called a till, cashbucker, or automated money handling system, is a mechanical or electronic device for registering and calculating transactions at a point of sale. It is usually attached to a drawer for storing cash and other valuables. A modern cash register is usually attached to a printer that can print out receipts for record-keeping purposes.
This article is about a machine that records sales and receipts. For computer hardware (i.e. POS cash register[1][2]) and software that does these tasks, see Point of sale.
