OEM SDC3 Mifare 13.56MHz RFID Proximity Fob Blue

OEM SDC3 RFID Fob

The OEM SDC3 Mifare Fob facilitates high-frequency proximity authentication for integrated access control environments. This hardware utilizes the 13.56 MHz frequency band to establish contactless communication between the credential and a compatible reader interface. It adheres to the ISO/IEC 14443A standard, ensuring broad compatibility with standard security infrastructure. The internal architecture features an integrated circuit with a dedicated antenna for efficient energy harvesting from the reader field. This blue proximity tag provides a reliable method for user identification without physical contact requirements.

Key Features

• High-Frequency Transmission
  The internal circuitry operates at a resonant frequency of 13.56 MHz for rapid data exchange.

• Robust Housing Construction

  • Ultrasonic welding seals the ABS plastic casing against moisture ingress.
  • The reinforced key ring hole prevents mechanical failure during high-cycle usage.

• Data Retention and Integrity
  The EEPROM storage maintains programmed data for up to ten years without power.

• Standardized Communication Protocol

  • Supports ISO/IEC 14443A transmission protocols.
  • Utilizes a 4-byte Non-Unique Identifier (NUID) for system registration.

Each blue HF security token contains 1KB of memory organized into 16 sectors. Each sector requires two functional keys for secure access to the stored data blocks. This hierarchical memory structure allows for multi-application support on a single device. The physical form factor measures approximately 40mm by 32mm, making it compact for attachment to standard keyrings. The passive design eliminates the need for internal batteries, as the device draws power directly from the electromagnetic field of the reader. Signal attenuation remains minimal within a 10cm read range, though performance varies based on the specific reader antenna dimensions. The ABS material resists common environmental stressors, including temperature fluctuations from -25 to +70 degrees Celsius. This ensures consistent performance in both indoor and outdoor terminal installations.
