MEFERI MS300R Bluetooth Ring Barcode Scanner

The MEFERI MS300R is a Bluetooth ring scanner worn on the finger, so warehouse and picking staff can scan barcodes with a press of the thumb and keep both hands free. At 77g, with an enterprise Zebra or Newland scan engine and IP65 sealing, it is built for full shifts of high-volume scanning.

Scan without picking anything up

With a handheld scanner, staff pick it up and put it down every time they handle an item. The MS300R sits on the finger with the scan button under the thumb, so pickers can lift boxes, open cartons and scan in one movement. It pairs naturally with the MEFERI ME10 wrist computer for a fully hands-free picking setup.

Ring or glove

Wear it as a ring with the Velcro finger strap, or clip it onto an optional MEFERI scanning glove, which has its own trigger in the palm. The scan button can be set up for left- or right-handed use.

Enterprise scan engines

The MS300R is available with Zebra SE4107, SE4750 or SE55 engines, or Newland engines. It reads 1D and 2D barcodes, including QR, Data Matrix and PDF417, at wide angles and in bright light. The long-range Zebra SE55 version reads larger labels from up to 15 metres away, for scanning racking locations from the floor.

One tap to pair

With MEFERI devices such as the ME10, pairing takes a single tap using NFC, so staff can grab any ring at the start of a shift and be ready in seconds. Standard Bluetooth pairing is also available. It supports Bluetooth HID (keyboard) mode, so scanned codes type straight into most Android apps.

Frequently asked questions

What does the MS300R connect to?

It connects over Bluetooth and is designed to work with the MEFERI ME10 wrist computer and other Android devices, including MEFERI handhelds. In HID keyboard mode, scanned barcodes appear in most apps as if typed. If you plan to use it with an iPhone, iPad or Windows PC, contact us first so we can confirm compatibility.

Can it be used in a freezer?

It is rated from -10°C to 50°C, so it suits chilled areas but not frozen storage. For freezer work, see the MEFERI ME74.
