RFID key fob Atlo ATLO-504/G — contactless proximity token, MPN ATLO-504/G

The Atlo ATLO-504/G is a compact RFID contactless key fob designed as a proximity token for secure identification and access control. Its small, durable form factor makes it easy to carry on keyrings and integrate into existing RFID systems that support standard low-frequency proximity credentials. The token communicates wirelessly with compatible readers to grant access, register time and attendance events, identify members, or tag assets where a convenient, non-contact credential is required.

Advantages

The key fob offers a lightweight and portable solution for everyday access control needs without physical contact. Its sealed casing provides basic protection against wear from daily handling and normal environmental exposure. The token is easy to deploy with compatible RFID readers and can be used in multi-device installations due to its standard proximity operation. The form factor reduces the risk of loss compared with loose cards and fits naturally on keyrings.

Suitable for

• Door entry systems and building access control
• Time and attendance registration
• Membership identification for clubs and facilities
• Asset tagging and simple inventory control
• Any application requiring a small, contactless credential

How to use

To use the Atlo ATLO-504/G key fob, present the token within the read range of a compatible RFID reader; the reader will detect the credential and process the associated ID according to the installed access control or identification system. No physical contact or line-of-sight is required. For initial setup, enroll the token’s identifier into your access control database, timekeeping system, or membership registry following the reader or system vendor’s enrollment procedure. Store and handle the fob like other contactless credentials to maintain reliable operation.

Usage recommendations

Register each token immediately upon receipt and maintain a secure record of issued credentials. Keep the fob away from strong magnetic fields and avoid immersion in water to prolong service life; replace tokens that show signs of physical damage. For optimal performance, ensure compatibility between the token’s frequency and your RFID readers before deployment.
