kártyaszám
Kártyaszám is a Hungarian term that translates to "card number." In its most common usage, it refers to the unique identifier assigned to a bank card, such as a credit card or debit card. This number is typically embossed or printed on the front of the card and is essential for completing transactions. The kártyaszám is usually a 16-digit number, though variations exist depending on the card issuer and type. It is composed of several parts, including a Bank Identification Number (BIN) which identifies the issuing institution, and a unique account identifier. For security reasons, it is crucial to protect one's kártyaszám and not share it unnecessarily. When making online purchases or providing card details over the phone, users are often asked for the kártyaszám along with other information like the expiration date and security code. The term can also, less commonly, refer to a serial number or identification number associated with other types of cards, such as loyalty cards or identification cards, but its primary association is with financial payment cards.
