RFID key fob Atlo ATLO-557NR/B, proximity access token, passive 13.56 MHz

Atlo ATLO-557NR/B is a compact proximity RFID key fob that operates at 13.56 MHz and functions as a passive access token. It contains a stored unique identifier that can be read by compatible ISO 14443/ proximity readers and integrated access control systems. The fob’s small, wearable design makes it convenient for everyday carry on key rings or lanyards and suitable for environments where a discrete, durable credential is required.

Advantages

The key fob provides contactless identification without an internal battery, offering low-maintenance operation and long service life under normal use. Its robust housing protects the RFID element from mechanical wear and everyday handling. The passive 13.56 MHz frequency ensures compatibility with a wide range of access control and identification systems that support high-frequency proximity tokens.

Suitable for

• Door entry systems and electronic locks
• Time-and-attendance and workforce identification
• Locker access and shared storage control
• Membership identification and access management in facilities

How to use

Present the fob within the read range of a compatible 13.56 MHz RFID reader until the reader acknowledges the identifier (visual or audible confirmation depends on the reader). No configuration or battery is required in the fob itself. For initial setup, register the fob’s identifier in the access control system or software according to the system operator’s procedures to assign access rights or user identity.

Usage recommendations

Store and carry the fob on a key ring or lanyard to keep it accessible. Avoid exposing the fob to strong magnetic fields, extreme temperatures, or prolonged immersion in water to preserve readability. For secure deployments, follow the access control system’s guidelines for enrollment, deactivation of lost tokens, and periodic review of access permissions.
