Chainway R3S is a desktop UHF RFID reader/writer with an integrated module and antenna that delivers reliable multi‑tag reading over a wide working area.
Powered by the Impinj E Series chipset with Gen2X support, it offers high sensitivity and stable tag identification even in dense tag environments.
Its slim, sealed housing and minimal footprint make it ideal for deployment on counters, desks, reception points and self‑service kiosks where space and cleanability matter.

Key features

• All‑in‑one near‑field UHF design with built‑in module and antenna for simple desktop integration.
• Impinj E Series with Gen2X support for accurate reads and strong performance in real‑world applications.
• Reads 70+ tags in a single scan (around 5 seconds) to accelerate inventory and checkout operations.
• 100+ cm read range with 30‑step adjustable RF output power for precise control of the reading field.
• High‑efficiency anti‑collision algorithms to maintain speed and identification rate when many tags are present.
• Multi‑platform compatibility with Windows, Android and iOS, supported by SDKs and developer documentation.
• LED status indicators and an integrated buzzer provide clear visual and audible feedback during reads.
• Top‑mounted physical Scan button so users can trigger reads directly from the device without relying on host input.​

Connectivity and deployment

• Interface options (model dependent):
  • USB Type‑C for direct connection to PCs, tablets or mobile terminals.
  • RJ45 Ethernet with PoE+ support for easy integration into fixed workstations and kiosks.
  • Dedicated DC input for stable external power in permanent installations.
  • Bluetooth 5.0 for wireless connectivity to mobile devices and POS systems.
• Power can be supplied via USB, Ethernet (PoE+) or DC, enabling flexible setups without complex rewiring.
• The compact desktop form factor allows the R3S to sit unobtrusively on counters, in front‑office areas or inside self‑service terminals.

RFID performance

• Supported standards: EPCglobal Class 1 Gen 2 / ISO 18000‑63 for wide interoperability with UHF EPC Gen2 tags.
• Frequency ranges: regional variants across 860–960 MHz (e.g. 865–868 MHz, 902–928 MHz) to meet local regulatory requirements.
• RF output power adjustable from 1 to 30 dBm in 1 dB steps, allowing fine tuning of read zone and sensitivity.
• Read rate up to 250+ tags per second, supporting fast bulk reading in busy environments.
• Typical read distance beyond 100 cm with suitable UHF tags (such as Impinj M750), depending on tag type and environment.

Typical applications

• Retail checkout and POS: fast item identification on counters and at cash desks for smoother customer service.
• Logistics and warehousing: desktop verification and short‑range inventory of cartons, trays and returnable assets.
• Identity verification and access control: reading RFID badges at reception desks, visitor registration points and controlled entrances.
• Smart parking and anti‑counterfeiting: validating RFID‑enabled tickets, cards or labels to improve security and traceability.
• Production process control: tracking components and work‑in‑process items at fixed workstations along the line.

Main benefits

• Wide working area and advanced multi‑tag performance that significantly improve operational efficiency on the desktop.
• Slim, fully sealed and unobtrusive design, easy to clean and suitable for environments that require a discreet and hygienic layout.
• Versatile connectivity via USB Type‑C, Ethernet/PoE, DC and Bluetooth 5.0 for straightforward integration into existing IT infrastructures.
• Cross‑platform support with SDKs for Windows, Android and iOS that shortens development time and speeds up RFID rollout.
• Impinj E Series and Gen2X technology for dependable, future‑ready UHF RFID performance in demanding, high‑density scenarios.
