Contactless access cards

Contactless card

— a flat electronic identifier that transmits a code to the reader for authorization in an access control system. The card is convenient for permanent employees, photo ID badges, and centralized tracking of issued identifiers. When choosing one, check the operating frequency and standard, such as EM-Marine or MIFARE, since cards that look similar may be incompatible. Also consider rewritability, the level of data protection, and support by the required controller.
