I want to create a portable scanner just like you see in supermarkets that checks the price. The materials I will be using are a usb barcode scanner, python, raspberry pi, and an lcd touchscreen. What GUI can I use to create this and also what database should I use? Please help! Need it to complete a school project.
Also how do I connect the scanner which gets data from the database with items to display to the GUI ? Just a beginner in python and rasp.
