MIFARE / EM RFID Key Fobs (Access Control Tags)

MIFARE and EM key fobs are compact RFID-based access credentials used in modern access control systems for secure and convenient entry management. These contactless tags operate at different frequencies—MIFARE at 13.56 MHz (high frequency) and EM at 125 kHz (low frequency)—making them suitable for a wide range of applications including office access, residential security, time attendance systems, and smart locks. Designed for durability and ease of use, these fobs can be easily attached to keychains and programmed into compatible access control systems for seamless authentication.
