n. A card, such as a credit card or debit card, which can be used for payment of goods or services.
A payment card is a device that enables its owner (the cardholder) to make a payment by electronic funds transfer. The most common types of payment cards are credit cards and debit cards. Payment cards are usually embossed plastic cards, 85.60 × 53.98 mm in size, which comply with the ISO/IEC 7810 ID-1 standard. They usually also have an embossed card number conforming with the ISO/IEC 7812 numbering standard.
Most commonly, a payment card is electronically linked to an account or accounts belonging to the cardholder. These accounts may be deposit accounts or loan or credit accounts, and the card is a means of authenticating the cardholder. However, stored-value cards are cards that store money on the card itself.
