A cashierless shopping store (10) including portable RF shopping terminals (34) carried by shoppers. Bar codes on purchased items are scanned using a RF shopping terminal before being placed in a shopping cart (210). The shopping cart detects the weight of items placed therein and conveys the weight informatio n to the RF shopping terminal over an RF communications link. The RF shopping termina l compares the weight information received from the shopping cart with the weight information read from the bar codes. If the weight information does not correlate, the RF shopping terminal signals a controller (52) to activate an alarm. When th e shopper wishes to pay for the purchased items, the shopping cart is wheeled to a cashierless checkout station (24). A lifting unit (304) lifts the shopping cart to detec t the weight of the purchased items and conveys the weight information to the RF shopping terminal. The RF shopping terminal again compares the weight information received from the lifting unit with the total weight information read from the scanne d bar codes. If the weight information correlates, the RF shopping terminal prompt s the shopper to enter a debit, credit or smart card into a card reader therein. Once the card is read, the RF shopping terminal prompts the shopper to entera PIN or password and then generates a financial transaction request. The financial transaction request is conveyed to a network controller (314) over an RF communication link. The network controller in turn conveys the financial transaction request to a financial institution for verification and processing. Once processed and verified, a verification is transmitted back to the network controller which in turn signals a printer (318) to prin t a receipt and open a gate allowing the shopper to leave with the purchased items.</SDO AB> |
