Description This product is not recommended for new designs. Instead, we recommend to use NXP’s MIFARE DESFire EV3 IC. NXP MIFARE® DESFire® EV1 4K cards are designed for diverse applications that demand the highest levels of security, including access control and biometric identification, cashless vending, public transportation, ticketing and customer loyalty cards. The MIFARE DESFire EV1 contactless IC is ideal for combining and supporting multiple applications on one contactless smart card or other form factor. 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 interface and cryptographic methods. It is compliant to all 4 levels of ISO/IEC 14443A 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 product-based smart card can hold up to 28 different applications and 32 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. The main characteristics of this device are denoted by its name “DESFire”: DES indicates the high level of security using a 3DES or AES hardware cryptographic engine for enciphering 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 experience convenient contactless ticketing while also having the possibility to use the same device for related applications such as payment at vending machines, access control or event ticketing. In other words, the MIFARE DESFire EV1 silicon solution offers enhanced consumer-friendly system design, in combination with security and reliability. 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. MIFARE DESFire EV1 contactless card delivers a 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. The DESFire EV1 fully compatible with the existing MIFARE reader hardware platform. MIFARE DESFire EV1 is your ticket to contactless systems worldwide. In other words, the MIFARE DESFire EV1 IC solution offers enhanced consumer-friendly system design, in combination with security and reliability. DESFire’s are available in PVC and Composite PET/PVC card construction. The MIFARE DESFire EV1 card is exceptionally durable and can accept an embeddable SAM card for logical access and biometric ID systems.
