RFID key fob Atlo ATLO-554N/B — contactless access token, passive 125 kHz compatible

Atlo ATLO-554N/B is a passive 125 kHz RFID key fob designed as a compact contactless access token. The fob communicates with standard low-frequency proximity readers to provide identification for access control, time and attendance systems, and asset or visitor management. Its small form factor and key ring hole make it convenient to carry and integrate into everyday use without batteries or maintenance.

Advantages

The contactless design enables quick, touch-free identification at compatible 125 kHz readers. Being passive, the key fob requires no internal power source, which reduces maintenance and extends service life. The durable enclosure resists everyday wear and can be attached to key rings or lanyards for easy access. Compatibility with common proximity systems simplifies integration into existing access control infrastructures.

Suitable for

• Door entry systems in offices, residential buildings, and facilities
• Time and attendance tracking for staff
• Asset tagging and basic inventory control
• Visitor credentials and temporary access tokens

Key specifications

• Technology: Passive RFID
• Operating frequency: 125 kHz (low frequency)
• Form factor: Key fob with key ring attachment
• Contactless read range: Typical proximity range for 125 kHz credentials (depends on reader).
• Power: No battery required

How to use

Present the key fob to a compatible 125 kHz proximity reader within the reader's specified range to register or verify identity. For enrollment, follow the access control system's registration procedure to associate the fob's identifier with a user profile. Once enrolled, the fob functions as an access credential; hold it near the reader until the reader confirms a successful read, typically indicated by light or sound. No charging or battery replacement is required.

Usage recommendations

Store the fob with other access credentials to prevent loss and avoid exposing it to strong magnetic fields or prolonged immersion in liquids. For reliable operation, test compatibility with your existing 125 kHz reader during deployment and follow the access control system vendor's enrollment procedures.
