MIFARE DESFire Light NFC contains features like the fully encrypted communication mode enabling contactless applications to address privacy sensitive applications. With its optional support of Random ID, it enables compliance with latest user data protection regulations. Users of MIFARE DESFire Light can change the application identifier (AID) and the file identifiers (FID) according to their needs enabling compatibility with existing data models. This further enables users to complement their use cases with an NFC forum-compliant Type 4 Tag in order to enable additional, end-user centric services, such as business card sharing or pairing with a network. MIFARE DESFire Light is compatible with MIFARE DESFire EV2, a secure multiapplication platform. Through this compatibility single application running on MIFARE DESFire Light can become part of a multi-application solution, combining applications from different entities, with minimal system impact. MIFARE DESFire Light is designed to support standards Class 1 smart cards antenna designs with a 17 pF input capacitance as well as smaller form factors, i.e. key fobs, wristbands, by providing 50 pF input capacitance delivery forms. This ensures high user convenience throughout different form factors.
MIFARE DESFire Light Card
NXP’s MIFARE DESFire Light is a contactless IC designed for easy integration into new and existing systems. Its predefined file system and total available memory of 640 Bytes (equivalent to MIFARE Classic® with 1 kB) make it an excellent choice for single-application designs in a wide variety of use cases. MIFARE DESFire Light is compatible with MIFARE® DESFire® EV2, so designers can easily expand their systems to support new applications. Compatibility with MIFARE DESFire EV2 also lets developers promote their services on NXP´s AppXplorer, a collaboration platform that creates an App Store-like experience on smart cards.
MIFARE DESFire Light can also be configured as an NFC Forum NFC Type Tag 4, so it’s ready to use with the broadest range of mobile devices equipped with contactless reading capabilities.
Designed for limited-and extended-use applications, MIFARE DESFire Light includes the appropriate protection mechanisms to power trusted services. Depending on the use case, up to five AES 128-bit keys can be used to manage access rights, while the secure messaging option enhances the protection of data and privacy. All of the chip’s hardware and software security features have been externally reviewed, tested, and certified according to Common Criteria EAL4.
