EFTPOS (Electronic Funds Transfer Point of Sale) is a device by which sales transactions can be directly debited to the customer's bank account at the point of sale, through the use of a debit card (generally the same card used with Automatic Teller Machines). Merchants using EFTPOS can also offer cashout facilities to customers, where a customer can withdraw cash along with their purchase. EFTPOS are sometime also called POS Terminal or Payment Terminal and must not be confused with traditional Point of sale.

The customer's card is swiped through a card reader and the merchant usually enters the amount of the transaction before the customer enters their account and PIN. There is usually a short delay while the EFTPOS terminal contacts the server (over a phone line or mobile connection) before a message of Accepted or Declined is returned. Often, at peak shopping times (for example the last shopping day before Christmas), the system can become overloaded and the delay will become extended or even time out.
