The GM-300B-2D is a handheld barcode scanner utilizing CMOS imaging technology. Unlike laser-based units, it captures and processes digital images, enabling it to decode both 1D (linear) and 2D (QR, Data Matrix, PDF417) symbologies. Due to its imaging sensor, it can read barcodes directly from digital screens (smartphones, monitors).
The device features a "Tri-mode" connectivity interface:
-
USB Wired (Direct cable connection).
-
2.4GHz Wireless (Via included USB dongle).
It includes an internal memory buffer (Storage Mode), allowing for data collection and batch transmission when the connection to the host is unavailable.
