Questions tagged [contactless-smartcard]

A contactless smartcard is a smartcard with a contactless communication interface in addition to or instead of a contact smartcard interface. Contactless smartcards are often used for ID documents and contactless payment cards (e.g. employee ID badges, electronic passports and ID cards and contactless credit/debit cards).

A contactless smartcard is a with a contactless communication interface in addition to or instead of a contact smartcard interface. Usually, the term "contactless smartcard" refers to a contactless transponder that adheres to the smartcard communication protocol standardized in ISO/IEC 7816-4 and that has a radio frequency interface according to ISO/IEC 14443. However, chip manufacturers sometimes also use the term "contactless smartcard" for contactless memory cards that have additional cryptographic and/or access control logic.
