Here are the input and output devices in a supermarket and their roles:
Cameras - These are input devices for the store security system. Their security office has computers, I/O storage devices (often hard drives), and monitors for output devices so their loss management team can watch suspicious customers.
Checkout lights - While not a computer component, these are output devices that let the customer know if the register is open or closed. If they are flashing, then that signals that a manager is needed, or that the cashier has left to get the manager or do a price check.
Keypads - These are input devices used for the cashier and/or the customer to enter data. For the cashier or manager, it is to enter price overrides and to enter prices or SKU codes of unmarked merchandise. For the customer, it is for entering their pin number.
Loss management sensors - These are primarily input devices in that they use RF signals to detect if there is unpaid merchandise. But they are also output devices when a detection is made, since they sound alarms and flash lights to alert the possibility of theft.
Price scanner - This is an input device that reads the UPC codes so the prices can be determined.
Receipt printer - This is an output device that prints the receipts for the customers. This could be a part of a cash register or a separate device that is attached to a point of sale system or computer.
Scales - These are primarily input devices in that they input data from the weight of the products. They are also used as security devices in self-check registers. They can also be output devices if they display the weight of the product.
Video terminals - These are output devices that are used to show the cashier and the customer the prices and to allow the cashier to operate the system. There are also video terminals in the security office.
