The MIFARE DESFire EV1 2K card from NXP Mifare DESfire family. it operates at 13.56 MHz frequency. it is NFC forum type 4. and according to the ISO 14443A standard with the transport protocol complying to the ISO 14443-4 standard. It features a 2K byte non volatile memory, a high speed triple-DES data encryption co-processor, a flexible memory organization structure, a mutual 3-pass authentication technique together with a true random number generator and an anti-tear mechanism to guarantee data integrity during contactless transactions. These MIFARE DESFire EV1 cards typically operate at a distance of up to 10cm depending on the power provided by the reader. Supplied as blank white printable PVC cards to ISO standard size and thickness.
MIFARE® DESFire® EV1 2K card 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® is your ticket to contactless systems worldwide.
