MIFARE DESFire EV1 is ideal for solution developers and providers wanting to combine   and support multiple applications on one contactless smart card. It fully complies with   the requirements for fast and secure data transmission, flexible memory organization, and   interoperability with existing infrastructure.
MIFARE DESFire EV1 is based on open global standards for both air interfaces and cryptographic methods. It is compliant to all four levels of ISO / IEC 14443 A and uses optional
ISO / IEC 7816-4 commands.
Featuring an on-chip backup management system and the mutual three pass authentication, a MIFARE DESFire EV1 card can hold up to 28 different applications and 32 files per application. The size and access conditions of each file are defined at the moment of its creation, making
MIFARE DESFire EV1 a truly flexible and convenient product. Additionally, an automatic anti-tear mechanism is available for all file types, which guarantees transaction oriented data integrity. With MIFARE DESFire EV1, data transfer rates up to 848 Kbit/s can be achieved, making fast data processing possible. The chip’s main characteristics are denoted by its name DESFire EV1, the first evolution of MIFARE DESFire: DES indicates the commitment for high levels of security -

Chip card, NFC CARD also referred to as IC, refers to the chip card as medium deal. Chip card capacity is very large, its working principle is comparable to a microcomputer, can have a number of functions concurrently. Chip card is divided into pure compound chip card and magnetic stripe chip card, now is its high security and multifunctional application is among the most development trend around the globe plastic card.
