MIFARE DESFire EV1

DESFire is an ideal solution for solution developers and system operators looking to combine different applications into one contactless smart card. It meets the requirements for fast and secure data transmission, flexible memory organization and is interoperable with existing contactless infrastructures.

It is based on NXP MF3 IC D41 and supports ISO 14443-4 protocol. It offers a number of security features such as cryptographic algorithms, on-chip backup management and mutual three pass authentication. Furthermore, it has an integrated proximity check function that prevents relay mifare desfire attacks and a key management system that can issue multiple versions of the master key. The chip also has a transaction timer to protect the device from man-in-the-middle attacks.

This makes MIFARE DESFire an ideal solution for a wide range of applications, such as access control and cashless vending. Additionally, MIFARE DESFire cards can be produced with visual security features such as holograms and ultra-violet fluorescent inks to help prevent counterfeiting.

MIFARE DESFire is a popular choice for campus ID cards, with many universities in Europe already using it to provide staff and students with access to services such as library and building access. The University of Bayreuth, Hogeschool-Universiteit Brussel and Southampton are some examples. These cards can also be used to pay for food and drink at cafes, and to gain access to printers, lockers and the university gym.

MIFARE DESFire EV2

Featuring NXP’s DESFire 4K chip, these MIFARE DESFire EV2 cards have a high-coercivity magnetic stripe. This makes it a good choice for contactless applications such as student ID cards, canteen and library access. The card has a data transfer rate of up to 848 Kbit/s and is compatible with most existing NFC readers. The MIFARE DESFire EV2 has an optional Secure Unique NFC (SUN) feature that adds a level of security to all interactions with the card. This consists of a cipher-based message authentication code that ensures the authenticity of all communications with the chip.

The IC is Common Criteria EAL5+ security certified, which is the same level of security that is demanded for the chips used in electronic passports. It also meets global standards for air interfaces and cryptographic methods, and it has a virtual smart card architecture that anticipates future privacy protection requirements.

MIFARE DESFire EV2 also includes a transaction timer that protects against Man-in-the-Middle attacks. This prevents someone from reloading your card and making fraudulent transactions. In addition, the IC has three decrement only counters to foil attempts to exploit timing vulnerabilities.

The DESFire EV2 IC is the best solution for students, staff and faculty who need to use their MIFARE DESFire card at multiple sites. It is compatible with most existing systems and provides more memory than previous versions of the MIFARE DESFire chip.

MIFARE DESFire EV3

The MIFARE DESFire family is the ideal solution for solution developers and system operators who require a reliable, scalable, flexible and interoperable contactless proximity transaction IC. The name “DESFire” refers to the IC’s use of 3DES or AES hardware cryptographic engines, which ensure confidentiality and integrity protection of transmission data. It is an open, scalable and secure microcontroller-based IC that can be embedded in smart cards, wearables & wristbands, paper tickets or banking convergence cards based on Near Field Communication (NFC).

The DESFire EV3 chips are the most advanced members of the MIFARE product family and meet industry demands for fast and reliable operation, enhanced security and high memory capacity. The MIFARE DESFire EV3 2K and 4K ICs offer the highest performance in its class, with up to 1 million read/write cycles and a maximum reading distance of 100mm. It also features an extended battery life up to five years for optimum operation, and supports the latest NFC Forum NFC Type Tag 4.

The DESFire EV3 offers multiple protection mechanisms such as mutual three-pass authentication and backup management systems, plus a variety of security keys to manage access rights and provide secure messaging. It is also Common Criteria EAL5+ security certified, a standard which is similar to that of smart card ICs for banking cards or electronic passports. HID credentials based on MIFARE DESFire EV3 chip can be used for access control, public transportation ticketing, cashless vending, or as loyalty or payment applications.

MIFARE DESFire Light

The MIFARE DESFire Light is an NFC smart card IC with an impressive array of security features. It includes mutual three pass authentication, a transaction counter and configurable secure messaging mode. It also supports up to five customer-defined AES 128-bit keys. In addition, the chip has a random ID and an anti-tear mechanism to ensure data integrity during contactless transactions. Its hardware and software are both certified to Common Criteria EAL4.

The DESFire EV3 is NXP’s latest chip generation, offering a high level of performance, security, flexibility and privacy. It uses the ISO/IEC 14443 Type A specification, and has a 3DES/AES hardware cryptographic engine to protect transmission data. It has improved operating distance and faster transaction speeds compared to previous MIFARE chips. mifare desfire It is also equipped with a new Transaction Timer feature that helps mitigate man-in-the-middle attacks.

The DESFire EV3 is designed to support standards Class 1 smart card antenna designs as well as smaller form factors like key fobs and wristbands, thanks to its 50 pF input capacitance delivery forms. It is also compatible with NFC mobile devices, as it uses the NFC-contactless communication protocol. The chip also meets the requirements of a wide range of international privacy protection regulations, such as the European Union’s General Data Protection Regulation (GDPR). It also supports the DESFire Authentication and Security Manager API to facilitate easy integration with third-party systems.
