Mifare

This trademark of NXP (formerly Philips Semiconductors) is the generic brand name of their PICC products. Billions of Mifare Classic cards have been deployed since the 90's. This is a family of wired-logic PICCs were data storage is divided into sectors and protected by a proprietary1 stream cipher called CRYPTO1. Every sector is protected by 2 access keys called 'key A' and 'key B'. NXP also offers another family of wired-logic PICCs called Mifare UltraLight (adopted by NFC Forum as Type 2 NFC Tags). Mifare SmartMX (and former Pro/ProX) is a family of microprocessor-based PICCs that may run virtually any smartcard application, typically on top a JavaCard operating system. Mifare Desfire is a particular microprocessor-based PICC that runs a single general-purpose application.
