What is the size of a credit card?

Most credit card cards comply with the international standard ISO/IEC 7810 [ID-1] and therefore have a uniform size of 85.60 length × 53.98 height x 0.76mm width. Having this international standard for card size is an essential part in the process of enabling consumers to use their credit accounts in almost every country around the globe. The ISO/IEC 7810 also sets minimum requirements for credit cards in terms of flammability, resistance to chemicals, resistance to heat, bending stiffness, and toxicity. Other types of cards that have an international standard under the ISO/IEC 7810 are passports [ID-3] and SIM cards [ID-000]. There are currently over 1 billion active credit cards in the United States with a combined debt of around $800 billion.
