CHECKOUTOPERATORS Supermarket Checkout operators sit at electronic tills and feed in the prices of the customer's goods. This is now done by 'scanning ' , passing each such item over 34 a device that reads the bar-code on it and automatically registers it down in the 35 till. They may weigh some products, such as fruit, on scales near the 36 till. When all the goods will have been scanned, the till provides a total and the 37 operators take payment in the cash, by cheque or by credit or debit card, and 38 give a till receipt and any more change required. They provide bags, often 39 help to pack purchases, and change paper till rolls as being necessary. 40 They also make it sure they have enough change, credit card forms , and carrier 41 bags. Operators ring a bell or buzzer to summon for a supervisor to help 42 with problems, and put notes and cheques into bags for periodic collection. 43 They enter their personal details in the till, so that their performance can be 44 analysed later. The system offers supermarkets an efficient way of handling with a 45 large number of customers purchasing many products and helps to keep checkout queues to a minimum. (34)
