MIFARE DESFire® EV1 4k Cards

 

MIFARE DESFire® EV1 is based on open global standards for both air interface and cryptographic methods. It is compliant to all 4 levels of ISO/IEC 14443A and uses optional ISO/IEC 7816-4 commands. MIFARE DESFire® EV1 delivers the perfect balance of speed, performance and cost efficiency. Its open concept allows future seamless integration of other ticketing media such as smart paper tickets, key fobs, and mobile ticketing based on Near Field Communication (NFC) technology. It is also fully compatible with the existing MIFARE® reader hardware platform. MIFARE DESFire® EV1 is your ticket to contactless systems worldwide.
