Electronic point of sale system
This is basically an electronic cash register that is linked to a computer, or that records data onto cassette or cartridge. In its simplest form, the electronic point of sale system may simply transmit details of a transaction to the computer for processing. The more complex terminals can communicate with the computer for such purposes as checking the credit position of a customer, obtaining prices from file and ascertaining availability of stock.
