A is a contactless 13.56-MHz credential whose dimensions are credit-card size. Its embedded integrated circuits can store and sometimes process data and communicate with a terminal via radio waves.
A contactlessis also characterized as follows:
- Dimensions are normally credit card The ID-1 of ISO/IEC 7810standard defines them as 85.60 × 53.98 × 0.76 mm (3.370 × 2.125 × 0.030 in).
- Contains a security system which is different for every brand tamper-resistantproperties (e.g. a secure cryptoprocessor, secure file system, human-readable features) and is capable of providing security services (e.g. confidentiality of information in the memory).
- Asset managed by way of a various central administration systems, or applications, which receive or sometimes interchanges information and configuration settings with the card. The latter includes card hotlisting, updates for application data.
- Card data is transferred via radio waves to the central administration system through card read write reader devices, such as access control mullion readers, ticket readers, ATMs, USB connected desktop readers or all devices embedding a contactless reader technology like printers, Time & attendance terminals, parking, lifts, point of sales, car sharing …
Contactless smart cards can be used for identification, authentication, and data storage. They also provide a means of effecting business transactions in a flexible, secure, standard way with minimal human intervention.
