Discover the convenience of wireless operation with the 2D HD3900 barcode scanner

The HD3900 is a practical scanner characterized by its multifunctionality and advanced features, allowing it to be used in virtually any location. It can be effectively applied in small shops, supermarkets, offices, and even logistics centers and warehouses. Equipped with a CMOS scanning matrix, this scanner enables the reading of leading one-dimensional and two-dimensional codes including QR and Aztec codes, both printed and displayed on LCD and LED/OLED screens, as well as on mobile devices. Moreover, the lack of moving parts in this matrix makes the scanner more resistant to damage than traditional laser scanners. An LED light for illumination and a targeting aid are also helpful for precise and comfortable scanning.
