electronic funds transfer at point of sale (EFTPOS) The automatic debiting of a purchase price from the customer's bank or credit-card account by a computer link between the checkout till and the bank or credit-card company. The system can only work when the customer has a
debit card or
credit card recognized by the retailer. In the increasingly widely used ‘chip and PIIN’ system the transaction is ratified by use of the customer's
personal identification number (
PIN), rather than by signature of a printed voucher.
