Barcode technology is the technical foundation for implementing POS systems, EDI, e-commerce, and supply chain management. At the same time, it is also an important technical means for the modernization of logistics management. This design is based on ST89C52RC microcontroller, using YHDAAM100 barcode scanning sensor for data acquisition, and finally displaying barcode data through LCD1602 liquid crystal. This design realizes the scanning code function under the condition of extremely low cost. The device is small in size and low in power consumption. Not only can it be used in portable barcode acquisition applications, but also has broad application prospects.
