A PDQ machine, also known as a Point-of-Sale (POS) terminal or card payment terminal, is a device used by businesses to accept electronic payments from customers. PDQ stands for "Process Data Quickly," highlighting the key function of these machines to swiftly process transactions.
PDQ machines are primarily used in retail environments, restaurants, or any business that requires the acceptance of debit or credit card payments. These devices allow customers to make purchases using their debit or credit cards by securely transmitting payment information to the card issuer's system for verification and authorization.
Typically, a PDQ machine consists of a small electronic device with a built-in display, a keypad, and a card reader. The customer inserts or swipes their card into the machine, and with the help of an encrypted connection, the necessary information from the card is read and transmitted to the payment processor for approval. The terminal then displays the approved status, and the customer can complete the transaction by entering their PIN or signing a receipt.
PDQ machines play a vital role in facilitating efficient and secure financial transactions, ensuring quick and accurate processing of payments. They are equipped with advanced encryption technology to protect sensitive cardholder data and comply with industry security standards.
In summary, a PDQ machine is a point-of-sale terminal that enables businesses to accept various forms of electronic payments, providing convenience and efficiency to both merchants and customers.
