ID-SL15 UHF RFID Sled Reader – 15m Range Bluetooth Handheld for Phones & Tablets | IDentium

The ID-SL15 is IDentium's in-house UHF RFID sled reader — an all-day, clip-on handheld that turns any smartphone or tablet into a 15-metre RFID scanner. Built on the ID_N710 UHF reader IC and paired with a 3 dBi circularly-polarised antenna on a 180° rotating hinge, it delivers B-class read performance without the cost or lock-in of a dedicated handheld terminal. Made in India · WPC-ETA · BIS Registered · ISO 9001:2015.

At a glance: 15 m read range · 200+ tags/second · 33 dBm RF output · 6,500 mAh all-day battery · Bluetooth 5.2 · IP54 sealing.

Why a Sled?

A dedicated handheld locks you into one vendor's screen, OS and refresh cycle. A sled doesn't. The phone your team already carries becomes the terminal — your own app, your own MDM, your own upgrade path — and the ID-SL15 supplies only the RFID physics. When the phone is replaced, the reader stays.

180° Rotating Antenna

The antenna wing folds flat against the phone for transport and rotates through 180° in use, so the operator can aim the beam at a shelf, a pallet face or the floor without changing grip or posture.

Optional 1D / 2D Scan Engine

An optional imager sits alongside the UHF antenna for sites that still run barcodes. It reads both 1D and 2D symbologies from a 640×480 CMOS sensor with white illumination and a 625 nm red aiming dot, and tolerates full 360° rotation with ±55° tilt and skew. A 1 W flashlight is built in for dark aisles and plant rooms.

• 2D symbologies: PDF417 · QR Code · DataMatrix

Software & Integration

Ships with an Android and iOS SDK plus a ready-to-run demo app, so an in-house team can add long-range RFID to an existing app without touching reader firmware. IDentium can also pre-integrate the reader with our platforms, shortening a deployment from months to weeks.

• SDK — Android and iOS libraries; inventory, single-tag read, write, lock and kill; power and session control
• Demo app — ready-to-run for bench evaluation and site trials
• ReaderSense — IDentium reader-management platform: device health, configuration, event routing
• Asset Management — IDentium platform: templates, locations, movements, audits, reports
• Data out — HTTP POST, WebSocket or direct database write

Typical Applications

• Utility & meter audits — verify meters, transformers and poles on the phone the lineman already carries
• Warehouse cycle counting — count a rack face from the aisle at 10–15 m instead of touching every carton
• Fixed-asset verification — annual physical verification across offices and plants, with no fleet of dedicated handhelds to maintain
• Retail stock-take — fast floor and back-room counts; staff use their own store phones
• Logistics gate-in / gate-out — read pallet and case tags at the dock door without a fixed portal
• Field service & maintenance — identify equipment, pull its history and log the job from one device

Ordering Variants
