HW-1266D Highly Sensitive 1D 2D QR Barcode Reader Module
The HW-1266D is a compact embedded barcode scan engine that supports accurate decoding of both 1D and 2D barcodes. Equipped with a 0.3MP global-shutter CMOS image sensor and high-speed scanning rate of 60 frames per second, it delivers smooth and efficient scanning performance with stable hardware configuration.
Its core strength lies in the perfect combination of self-developed advanced decoding algorithms and Ingenic processor, offering strong compatibility and stability in various environments. It effectively solves the difficulty of scanning screen codes under strong sunlight reflection, and reliably reads special codes such as Datamatrix inverse codes on Russian cigarette packs and PDF417 codes on wine bottles. Supporting more than 30 languages and special characters, it is compatible with global data formats including UTF-8, GBK, and UNICODE to meet international application requirements.
Key Features

Applications
As a key sensing component in the IoT ecosystem, the HW-1266D embedded scan engine is designed for device integration and widely used in various fields:
- Handheld devices: Wired, wireless, and Bluetooth barcode scanners for retail, logistics, hospitals, industrial manufacturing, and warehouses
- Self-service equipment: Ticket checkers, vending machines, queuing machines in hospitals and government service centers
Note: For access control systems, our modular scan engines are recommended due to wider scanning area and shorter working distance for better matching.
