GEM-2D - Wireless 1D/2D Barcode Reader

Designed to work directly with GEM-CAR via a wireless USB key (USB receiver): Plug-and-play, no driver installation required.
Supports standard 1D codes, 2D codes (QR, DataMatrix, PDF417), and even GEM-CAR specific labels.
Operating modes:- Instant Upload (direct upload to GEM-CAR)- Memory mode (up to 150,000 scans stored)- Wireless range up to 100 m in open field. - Compatible with Windows and macOS, and therefore with stations running GEM-CAR.

This is the official model promoted for GEM-CAR:

Wireless Barcode Reader

We recommend the following wireless reader, which can easily be found on websites such as Amazon: Tera Barcode Scanner 2D Wireless Wired with Battery Level Indicator 1D 2D QR Digital Printed Bar Code Reader Cordless Handheld Plug and Play Barcode Scanners for Warehouse Supermarket D5100.

How it Works with GEM-CAR

Plug the USB receiver into your Windows PC where GEM-CAR is installed.
The reader connects automatically (plug-and-play).
Open GEM-CAR and scan a barcode (product, job code, VIN).
The software captures the data directly from the reader.
GEM-CAR recognizes wireless scanners as standard keyboard input.

Other Compatible Alternatives (USB/Bluetooth)

Although the GEM-2D is the official option, other “universal” wireless scanners will also work with GEM-CAR, provided they are recognized as a keyboard or HID device by Windows:

Wireless 2D Readers to Consider

The following models are solid options if you want to explore other brands (usually work in HID mode via Bluetooth or USB key):

Universal Bluetooth 2D readers (scan QR + 1D codes) – Windows compatible
2.4 GHz wireless USB readers with receiver (similar to GEM-2D)
Scanners with charging base + stand for workshop

Check that the Reader Supports:

1D + 2D (Code 39, Code 128, EAN, QR, DataMatrix, etc.)
HID keyboard mode so that GEM-CAR can read it directly. Examples of compatible styles: portable Bluetooth 2D readers or 2.4 GHz wireless USB scanners (often sold on BestBuy and professional websites).

Purchasing Advice:

- 1D only? OK for certain product uses, but less flexible.

- 2D/QR required? Yes, if you want to scan QR codes or certain advanced VIN formats.

- Bluetooth vs. wireless USB? Bluetooth: good for tablets or mobile devices.

- Wireless USB (dongle): often more stable with Windows PCs (standard GEM-CAR use).
