Non contact IC card Philips NXP Mifare DESwire (MF3) D21 D41 D81

MIFARE DESFire EV1 fully meets the needs of fast and highly secure data transfer, flexible memory structure, and compatibility with existing infrastructure, making it ideal for service providers who want to use multifunctional smart cards for transportation systems, e-government, or identification applications.

MIFARE DESFire EV1 is based on the global open standard air interface and encryption method, fully compliant with the four levels of ISO/IEC 14443A standards, and specifically uses the ISO/IEC 7816-4 instruction.

The MIFARE DESFire EV1 chip card is equipped with an embedded backup management system and three two-way authentication. One card can store up to 28 applications, with 32 files for each application. The initial design allows for the size of each file to be set, making it a truly flexible and convenient product.

In addition, all file types have an anti tamper mechanism that ensures the integrity of exchanged data. Through MIFARE DESFire EV1, the data transfer speed can reach 848 Kbit/s, enabling fast data processing.

The main characteristics of the chip used in this IC card are implicit in the product name. DES stands for MIFARE DESFire EV1, which uses the 3DES hardware encryption engine to transcode transmitted data to achieve a high level of security; Fire means that we aim to win a leading position in the non-contact close range transmission market in terms of speed, innovation, reliability, and security. Therefore, MIFARE DESFire EV1 brings many benefits to the general public. Cardholders can also use the same card for other related applications while experiencing convenient contactless ticketing applications, such as paying for items purchased from vending machines, using it for access control or event tickets. In other words, the MIFARE DESFire EV1 silicon solution combines security and reliability, and is sure to bring system designs that are favored by consumers.

MIFARE DESFire EV1 achieves the best balance between speed, performance, and cost-effectiveness. The open concept of the system allows for seamless integration with other ticketing tools in the future, such as smart tickets, key fobs, and mobile ticketing using NFC short-range wireless communication technology. It is also fully compatible with existing MIFARE card reader hardware platforms. MIFARE DESFire EV1 is your passport to the contactless world.
