Compact plug-and-play UHF RFID reader
Compact plug-and-play UHF RFID reader designed for direct connection to compatible devices running JAMS. The JR1 provides convenient short-range jewellery tag scanning through a direct USB Type-C connection, making it ideal for individual product identification, verification and day-to-day counter operations.

Overview
The GEM Reader JR1 is a compact UHF RFID reader designed for direct connection to compatible devices used with the JAMS Jewelry Asset Management System.
Its small form factor allows the reader to connect directly to a compatible device without requiring a separate desktop reader, external power supply or complex installation.
The JR1 is designed for short-range RFID reading, making it particularly suitable for jewellery counters and individual product operations. Staff can simply bring a tagged jewellery item close to the reader to identify the product within JAMS.
The intentionally limited reading range helps provide controlled item identification while reducing unwanted detection of other RFID-tagged jewellery nearby.
Its compact and lightweight design makes the JR1 particularly useful for mobile and counter-based JAMS installations.
