Nowadays It realized the self-service through vending machines with a barcode scanning engine, and takes more convenience and saves more time.
How does a QR code scanner work in vending machines?
first, connect with the barcode scanning module to the host and power supply, sometimes the power supply is provided by the host, otherwise, it needs to connect to an external power supply, it depends on the on-site environment, most mini barcode scanner modules are with TTL232 or USB interface, then you should shut down the host until it connects well, second, setting the communication of barcode scanner and the host by scanning the code on the user manual, the data can be upload to the PC
With the rapid development of the IoT, there are more and more smart devices using embedded barcode scanning modules. as an accessory that integrates the payment scanning function, it gives full play to the functions of automatic identification, collection, and transmission, and helps merchants expand payment channels at the same time.
