The RFID Tag - FR285 13.56MHz RFID Key Fob is a compact and durable contactless RFID transponder designed for secure identification, authentication, and access control applications. Operating at a frequency of 13.56MHz, the key fob is based on the ISO/IEC 14443A standard and is compatible with a wide range of RFID readers and embedded systems. Its lightweight construction, waterproof housing, and convenient keychain design make it ideal for access control systems, attendance monitoring, security applications, smart locks, parking management, time recording systems, and Arduino, ESP32, Raspberry Pi, and other RFID-based electronics projects.
Powered by passive RFID technology, the FR285 RFID Key Fob requires no internal battery and draws operating power directly from the electromagnetic field generated by a compatible RFID reader. It features a unique factory-programmed identification number and provides fast, reliable, and contactless data transmission. Its robust ABS enclosure protects the internal RFID chip from dust, moisture, and daily wear, making it suitable for both indoor and outdoor environments.
The RFID Tag - FR285 operates at the globally accepted 13.56MHz high-frequency (HF) RFID band and is compatible with MFRC522, PN532, RC522, and other ISO/IEC 14443A compliant RFID reader modules. The compact key fob design easily attaches to keyrings, ID holders, bags, or lanyards, making it convenient for everyday use. It is widely used in residential access control, office security, educational institutions, hotels, hospitals, industrial facilities, and embedded RFID development projects.
Designed for students, hobbyists, makers, engineers, researchers, and professional system integrators, the RFID Tag - FR285 13.56MHz RFID Key Fob is suitable for Arduino IDE, ESP-IDF, PlatformIO, MicroPython, Raspberry Pi, STM32, and numerous embedded development environments. Its universal compatibility, maintenance-free operation, and reliable performance make it an excellent choice for RFID learning, automation systems, IoT projects, and commercial access control solutions.
