Key fob Atlo ATLO-505/G RFID with programmable UID, proximity access token

The Atlo ATLO-505/G is an RFID proximity key fob with a programmable UID designed for contactless identification and access control. Its compact, durable housing is intended for everyday carry on key rings and provides a convenient credential for RFID readers in door entry systems, time & attendance terminals, and asset tagging applications. The modifiable UID allows integration with existing systems that require custom identifiers or UID cloning for authorized devices.

Advantages

The key fob offers a small form factor for easy attachment to keys and lanyards, combined with reliable proximity reading at short range. Programmable UID capability enables flexible deployment across different RFID access control setups without replacing existing infrastructure. The construction is durable for daily use and suited to environments where a lightweight, tamper-resistant token is preferred.

How to use

Present the key fob to a compatible RFID reader within the reader's effective range to register an access event or identify the holder. To program or modify the UID, use an appropriate RFID writer or configuration tool that supports writing the device's UID format; follow the writer manufacturer's instructions and ensure you have authorization to change identifiers. After programming, test the fob at the target reader to confirm recognition and correct access permissions.

Usage recommendations

Store the fob on a separate key ring or lanyard to avoid mechanical stress. When programming the UID, back up existing system mappings and verify compatibility with your access control system to prevent conflicts. Avoid exposing the device to prolonged moisture or extreme temperatures to maintain reliable performance.
