1.Most grocery stores use bar code scanning technologies that interface with cash registers used to process customer purchases. Cashiers use the scanners to read bar code labels attached to each product, which the system then uses to obtain unit prices, calculate transaction totals, including sales taxes, and update perpetual inventory databases.

Along with the scanning technologies, groceries use point of sale technologies that allow customers to swipe debit and credit cards for payment, while still maintaining the ability for customers to pay with cash.
