13.56 MHz RFID Cards

What is a 13.56 MHz RFID card?

A 13.56 MHz RFID card is a contactless card that works at high frequency (HF) and uses the ISO/IEC 14443 A standard. 13.56 MHz is an operating frequency, not a chip brand: different manufacturers make different chips for it. Unlike a 125 kHz proximity card with a read-only number, data can be written to the memory of these cards, so they are used in hotel door locks, canteen and cashless payment systems and campus or company ID cards.
