Creditcardsized

Creditcardsized is a term used to describe objects that adopt the external dimensions of a standard credit card. The most common size is defined by ISO/IEC 7810 as ID-1: 85.60 mm in length and 53.98 mm in width, with a nominal thickness of 0.76 mm. Real-world cards can vary slightly due to manufacturing tolerances and occasional thickness variations. The term is used both to describe actual cards and as a design target for non-card items intended to be compact and wallet-friendly.

In practice, creditcardsized items include plastic loyalty or access cards, debit and credit cards, and identification badges. They are also used in product design for devices intended to be carried in a wallet or cardholder. This format is popular for hardware and promotional products that benefit from portability, such as wallet-sized USB drives, credit-card-shaped power banks, or compact development boards.

Design considerations for creditcardsized objects often emphasize rounded corners, smooth edge finishing, and durability given the thin profile. The standard size helps ensure compatibility with card readers, card slots, and wallets, but it can constrain internal volume and mechanical robustness. Manufacturing tolerances and edge treatments are important to maintain usability and longevity.

Variants and adaptations exist for applications requiring different thicknesses or profiles while retaining a card-like footprint. Some contactless cards or RFID-enabled items use the ID-1 dimensions to ensure compatibility across readers and wallets.
