NXP’s MIFARE®DESFire®Light is a contactless IC designed for easy integration into both new and existing systems. It features a predefined file system and a total of 640 bytes of available memory (equivalent to 1 KB on MIFARE®Classic®), making it an ideal choice for single-application designs across a wide range of use cases. MIFARE®DESFire®Light is compatible with MIFARE DESFire EV2, allowing designers to easily expand their systems to support new applications. Compatibility with MIFARE DESFire®EV2 also allows developers to promote their services on NXP’s AppXplorer, a collaborative platform that creates an App Store-like experience on smart cards. MIFARE DESFire Light can also be configured as an NFC Forum NFC Type 4 tag, making it ready for use with a wide range of mobile devices equipped with contactless reading capabilities. Designed for both limited and extended-use applications, QOOB®MIFARE®DESFire®Light includes appropriate protection mechanisms to deliver trusted services. Depending on the use case, up to five AES 128-bit keys can be used to manage access rights, while secure messaging options enhance data and privacy protection. All of the chip’s hardware and software security features have been externally reviewed, tested, and certified to Common Criteria EAL4.
