RFID key fob Atlo ATLO-504N/G — proximity access token, passive 13.56 MHz

The Atlo ATLO-504N/G passive RFID key fob operates at 13.56 MHz and is designed for proximity access and identification systems. Compact and lightweight, this key fob provides a practical form factor for everyday carry on keyrings while enabling user authentication for door entry, time and attendance systems, and simple asset tagging when used with compatible RFID readers that support standard 13.56 MHz tags.

Advantages

The key fob offers passive operation, meaning it requires no internal battery and is powered by the reader field, which simplifies maintenance. Its durable casing protects the internal RFID chip and antenna against everyday wear. The compact design is convenient for attachment to keys or lanyards and supports quick, contactless identification at a typical proximity distance for 13.56 MHz systems.

How to use

Present the key fob to a compatible 13.56 MHz RFID reader or terminal until the reader indicates a successful read, typically by a light or sound. There is no setup on the fob itself; registration and encoding of the identifier are performed via the access control or identification system during enrollment. Keep the fob free of heavy scratches or cracks to maintain reliable read range and physical integrity.

Usage recommendations

Register each key fob in your access control or attendance system immediately upon distribution. Avoid exposing the fob to extreme temperatures, prolonged UV light, or strong mechanical impacts. For optimal performance, keep the fob a few centimeters from the reader antenna and follow the reader manufacturer’s placement guidance.
