Electronic cash register

Many businesses use cash registers to facilitate purchases of goods or services by purchasers using currency, checks or transaction cards. The electronic cash register is usually used in a shop, restaurant, department store or other stores for registering sales of commodities or goods sold to a customer. An electronic cash register (ECR) include a key board including article keys, function keys, and a total key, a microprocessor for processing, and a display such as an LCD, for displaying the result of the calculation. A keypad on the cash register may be used by the cashier to enter the costs of individual items and to determine the total amount owed by the purchaser for goods or services purchased. Alternatively, a bar code scanner may be used as a means for inputting the identification and cost of items to the computer. The cash register's computer generally records information for each transaction made using the cash register during a controllable time period. This recorded transaction data is used to determine total cash receipts for each cashier's shift for reconciling net receipts during that shift on that cash register. Cash registers generally have a cash drawer that slides out at the appropriate time in the transaction to reveal a plurality of compartments, where each compartment is designed to accommodate one stack of bills of a common denomination. The electronic cash register is generally connected to a printer and a display as standard output devices which respectively print out and display output data.
