High-performance decoding chip capable of reading 1D and 2D barcodes. Uses CMOS image scanning technology to scan both printed and screen-displayed barcodes. Designed to reliably decode incomplete or blurry barcodes. Decode Types: 1D: CODE 128, EAN-13, EAN-8, CODE 39, UPC-A, UPC-E, CODABAR, INTERLEAVED 2 OF 5, CODE 93, UCC/EAN-128, GS1 DATABAR, etc. 2D: QR Code, Data Matrix, PDF417, etc. Constructed from high-quality ABS material for durability. Suitable for applications including access control systems, elevator control, visitor management, and other industrial automation scenarios. A modern upgrade to traditional card-swipe systems. Optical Resolution: 640 × 480 CMOS Scanning Mode: Inductive Reading Scanning Accuracy: 4 mil Maximum Current: 230 mA Operating Temperature: 0°C to 50°C Storage Temperature: -40°C to 60°C Operating Humidity: 5%–95% relative humidity (non-condensing) Color: White Material: ABS Package Contents: 1 × Embedded Barcode Scanner Module Note: Color appearance may vary slightly due to screen settings and lighting conditions. Measurement tolerance: ±1–3 cm.
