POP systems, more commonly called point-of-sale or POS systems, frequently use hardware or software systems tailored to the particular industry or business. Although some small retailers still use off-the-shelf cash registers to calculate payment amounts and issue receipts, most POS systems today are computer-based and incorporate other devices or peripherals, such as printers, bar code scanners, scales and touch screens. In some cases, customers perform the duties that were previously performed only by check-out clerks, such as scanning bar codes, weighing items that are sold by weight, operating POS terminals by tapping their fingers against touch screens, and making payments by swiping their credit cards or inserting cash into machines.
