Access to guarded zones or services granted on the basis of identity credentials is crucial in many applications, hence sophisticated encryption methods are necessary to maintain a high level of security in access control, payment or public transport applications. The NXP company and the MIFARE® DESFire® open standard developed by it since 2002, which from 2020 is already available in the EV3 version, comes to the rescue of these safety requirements.

The name DESFire refers to the use of hardware cryptographic engines DES, 2K3DES, 3K3DES and AES to secure data transmission. The MIFARE® DESFire® contactless integrated circuits are based on the 8051 processor with the 3DES/AES cryptographic accelerator, which enables very fast transactions. The MIFARE® DESFire® standard is ideally suited for integrators and system operators building reliable, interoperable and scalable proximity solutions. The DESFire standard will seamlessly integrate with mobile systems and can support multi-application smart card solutions in credentials, access control, loyalty programs and micropayments, as well as in public transport ticketing.

To read data from MIFARE® DESFire® transponders, appropriate readers or embedded modules are required. Netronix offers ready DESFire solutions compatible with the ISO/IEC 14443-2/3A contactless interface, working at a frequency of 13.56MHz and embedded modules, adapted for discreet assembly in customer applications.
