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 is main characteristics are  denoted by its name DESFire EV1, the first evolution of MIFARE DESFire: DES  indicates the commitment for high levels of security

                An easy Search engine for credit card rfid hack arises numerous YouTube videos of hacks, and in many cases step-by-step outlines. More unnerving is the realization that contactless readers can be purchased on eBay for as low as $50. But while RFID bank card supporters claim cards has to be one-three inches from the reader to pull data, eliminating the opportunity of falling victim to theft, long-distance reading has actually been around for a time.NFC CARD
