Scanner modules and engines deliver strong decoding performance with high efficiency. They support both manual and automatic continuous scanning modes. Users can scan barcodes quickly and flexibly in various scenarios. These devices easily read reflective, blurred, or colored barcodes. They decode smoothly in both bright and dark lighting conditions. Scanner modules and engines are widely used in barcode payment, access control systems, Máy bán vé, self-service terminals, and reverse vending machines (RVMs) for circular barcode recognition.
