A MIFARE card is a popular type of contactless smart card from NXP, operating at 13.56 MHz (ISO 14443A standard) for secure, fast transactions, widely used in access control, public transport, loyalty programs, and payments, featuring memory (like 1K) and unique data for various applications. While MIFARE Classic has security weaknesses, newer types like MIFARE Plus and MIFARE DESFire offer enhanced security for multi-application systems, even working with NFC phones.
