It is fullycomplies with the requirements for fast and highly secure data transmission, flexiblememory organization and interoperability with existing infrastructure.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 optionalISO/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 and32 files per application. The size of each file is 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 transferrates up to 848 kbit/s can be achieved, allowing fast data transmission.The main characteristics of this device are denoted by its name \"DESFire\": DES indicatesthe high level of security using a 3DES or AES hardware cryptographic engine forenciphering transmission data and Fire indicates its outstanding position as a fast,innovative, reliable and secure IC in the contactless proximity transaction market. Hence,MIFARE DESFire EV1 brings many benefits to end users. Cardholders can experienceconvenient contactless ticketing while also having the possibility to use the same devicefor related applications such as payment at vending machines, access control or eventticketing. In other words, the MIFARE DESFire EV1 silicon solution offers enhancedconsumer-friendly system design, in combination with security and reliability.MIFARE DESFire EV1 delivers the perfect balance of speed, performance and costefficiency. Its open concept allows future seamless integration of other ticketing mediasuch as smart paper tickets, key fobs, and mobile ticketing based on Near FieldCommunication (NFC) technology. It is also fully compatible with the existing MIFAREreader hardware platform.
