The MEFERI MS300R is a compact wearable ring barcode scanner with Bluetooth 5.0 and NFC capabilities designed for hands-free scanning in warehouses, retail, logistics and other high-mobility environments.
It supports Bluetooth 5.0 for wireless data connection to host devices and includes NFC functionality. The device also has a USB 2.0 interface and a 2-pin bottom pogo connector for charging/cradle use.
Typical pairing steps: charge and power on the scanner, enable Bluetooth on your host device, put the scanner into pairing mode (see user manual), then select the device from the host's Bluetooth list. If NFC pairing is supported for your configuration, tap the scanner to the host's NFC zone to initiate pairing. Refer to the supplied manual for exact button sequences and any PIN codes.
The product specification lists the scan element type as 'Other' and does not enumerate symbologies. Many wearable scanners support common 1D and 2D codes, but please check the detailed datasheet or contact the vendor to confirm which barcode types (e.g., Code128, EAN, QR) are supported.
Bluetooth 5.0 generally provides improved range over older versions, but actual range depends on the environment and host device. Expect typical indoor ranges of roughly 10–30 meters; for exact range performance in your environment, test in situ or consult the vendor.
The scanner can be charged via its USB 2.0 connection or a 2-pin pogo pin cradle. The specification does not list battery capacity or run-time — check the product datasheet or ask your supplier for expected battery life under your usage pattern.
Yes — the MS300R is a wearable ring-style scanner designed for hands-free operation. It is typically mounted on a finger using an adjustable strap or ring. For wearing instructions, trigger locations and fit recommendations consult the user manual supplied with the unit.
Wearable scanners like this commonly work with Windows, Android and iOS hosts, especially when they support standard Bluetooth profiles (HID or SPP). The MS300R includes an SDK for integration — check with the vendor for supported Bluetooth profiles and SDK language/platform support for your application.
The MS300R ships with an SDK to support custom application development. Contact the supplier for SDK documentation, sample code, supported platforms and APIs (e.g., HID, serial or custom libraries) so you can integrate scanning into your software.
The specification does not explicitly state multi-host capability. Some wearable scanners pair to one host at a time while others support multi-host or fast switching. Confirm multi-host or multi-pairing behavior with the vendor or the product manual.
According to the product information, service options include return and replacement, repair, free spare parts, onsite training and inspection, as well as call center and online technical support. Check your seller's warranty terms for specific coverage and support contact details.
The single package size is listed as 19 x 20 x 10 cm and the single gross weight is 1.500 kg. For a complete accessory list and exact box contents, consult the seller or the packing slip.
Turn the device off and remove it from the finger mount before cleaning. Use a soft, slightly damp cloth with mild detergent; avoid solvents, abrasive materials and excessive moisture. Keep the pogo pins and charging contacts dry and clean. Refer to the user manual for any manufacturer-recommended maintenance procedures.
Basic troubleshooting: ensure the battery is charged, check Bluetooth pairing and signal strength, verify the barcode symbology is supported and not damaged, clean the scanner window, restart both scanner and host device, and test with a different host or USB connection. If problems persist, consult the SDK logs (if available) or contact technical support.
