WS-SMD-QRCODER combines with video transmitting sensor technology, lighting, and optics technology to identifying and reading codes and pictures in all-direction. It uses it transmitted infrared, and base on results of its reflections then decode by using this chip. Finally, it returns to the representative correct character of barcode. It is through difference in the degree of infrared reflection between black and white to judge barcode width. Built-in sensor. Depending on the different intensity of the reflected light to generate different voltages and generates the logic data in further. The minimum depth of field be determined by code length and scanning angle, also it is depending on code’s resolution, contrast, environment light. Easy to Identification QR code, barcode, barcodes on the display screen, barcodes of various materials, barcodes of coated films, dirty barcodes, and wireless bar code, and transmit to far-end through WiFi or transmit data by RS-485. Users use mobile App to type in related settings and translate to QR code, and use WS-SMD-QRCODER scanning then that enables to complete all settings. It is easily to operate and setting to construct WiFi environment. This product enables to be widely applied on the related fields of inventory management, electronic tickets, electronic voucher, logistics, and so on.
