Description
The Chainway R3S is a desktop UHF RFID reader for counters, kiosks and back-office asset tracking. Its all-in-one design has an integrated UHF module and antenna, so you connect a cable, place the reader on the counter and start reading tags.
The reader uses an Impinj E Series chipset with Gen2X support, a 30-step adjustable output power and a physical scan button. Chainway lists the R3S for desktop use or for kiosk integration in retail checkout and high-value asset management.
Reading performance
The R3S reads 70+ tags in one scan within five seconds and has a fastest read rate of 250+ tags per second. The output power runs from 1 to 30 dBm in 1 dB steps. Chainway rates the maximum read range at more than 100 cm when reading the Impinj M750 test tag. Actual range depends on the tag and the environment.
Connections and power
The base version has one USB Type-C port. The Enhanced version adds a DC input (+8 V to +28 V), and the PoE version adds an RJ45 port that supports PoE+ (IEEE 802.3at, 25.5 W). Ethernet runs at 10/100 Base-T, and Bluetooth 5.0 (BLE) is built in for wireless pairing with a host device.
Software and platforms
Chainway provides an SDK for Android, iOS and Windows, so the reader can be integrated with a POS application, a kiosk or a custom asset-tracking system.
