RFID key fob Atlo ATLO-554N/W — proximity token for access control, passive 125 kHz/13.56 MHz compatible

Atlo ATLO-554N/W is a compact RFID key fob designed as a passive proximity token for access control and identification. Compatible with 125 kHz and 13.56 MHz systems, the key fob provides contactless credentialing for door entry, time attendance terminals, and other access-managed devices. Its small, durable housing is intended for everyday carry on keyrings and for use in environments that require simple, reliable proximity authentication.

Advantages

The token supports both low-frequency and high-frequency RFID standards, allowing flexible integration with a range of access control readers without the need for internal power. Its compact and lightweight design resists everyday wear while remaining easy to attach to keys or lanyards. Passive operation ensures long-term use without battery maintenance, and the sealed housing offers protection against dirt and moisture typically encountered in daily access scenarios.

Suitable for

• Door entry systems in residential and commercial buildings
• Employee time and attendance terminals
• Controlled access to shared facilities such as gyms or storage rooms
• Temporary or visitor identification when issued alongside managed access

How to use

Present the key fob to a compatible RFID reader’s sensing area at a short distance until access is granted or the reader indicates authentication success. No batteries or activation steps are required; the reader supplies the necessary power when the fob is within range. For first-time use, the fob must be enrolled in the access control system by an administrator following the system’s enrollment procedure.

Usage recommendations

Store the key fob on a keyring or lanyard and avoid exposing it to strong magnetic fields or prolonged immersion in water. Register and deactivate lost or stolen tokens promptly through your access control administrator to maintain site security.
