RFID proximity key fob Atlo ATLO-505/N with writable/modifiable UID

Atlo ATLO-505/N is an RFID proximity key fob with a writable, modifiable UID designed for access control and identification systems. This compact contactless token provides a programmable UID that can be set to match existing databases or reader expectations, allowing straightforward integration with readers that accept custom UID programming. The fob is suitable for managing user credentials in environments where compact, durable tokens are preferred.

Advantages

The writable UID enables flexible credential management and simplifies replacement or reprogramming without changing physical tags. Its compact, lightweight design makes it convenient to carry on keyrings or attach to lanyards. The contactless nature reduces wear compared with mechanical keys or magnetic stripes, and the standard proximity form factor ensures compatibility with many common RFID readers.

Suitable for

• Keyless entry systems for offices and residential buildings
• Time and attendance tracking
• Locker and cabinet access control
• Asset tagging and inventory control in small-to-medium installations

Key specifications

• Type: RFID proximity key fob with writable/modifiable UID
• Form factor: Compact contactless token suitable for keyrings
• Compatibility: Works with readers that support writable UIDs and standard proximity protocols
• Durability: Designed for everyday carry and contactless use

How to use

Program the fob's UID using a compatible RFID writer or reader that supports UID modification, following the writer's instructions for setting a new identifier. After programming, register the UID in your access control or management system according to its enrolment procedure. Use the fob by presenting it near the reader antenna; the reader will read the programmed UID and grant or deny access based on your system's configuration.

Usage recommendations

Store and handle the key fob to avoid strong mechanical impact. When programming, verify that your reader/writer supports UID writing for this tag type and that written identifiers are unique within your system to prevent credential conflicts.
