Mifare Classic

Introduction

Launched in 1995, the MIFARE S50 (MIFARE 1k) IC was the first product, which could be fitted into an ISO contactless smart card and with its slim coil, allowed very high volume production. Expanding on the functionality of the existing MIFARE S50 (MIFARE 1k) ICs, the MIFARE S70 (MIFARE 4k) IC was developed. It provides significant increased memory size, making it the perfect solution for multi-application cards. It allows end-users to be more flexible and to experience improved convenience.
