I got from a barcode scanner (external device) a database with approxemately 70 products. At every scanning i got a Rs 232 signal with the barcode detail.
I need to get these signals to a raspberry device for local storage and then upload them to a website where the final customer will have the option to get statistics related to products, price, time or different shops.
The raspberry will also have the option to turn on-off a dry contact (relay). The contact will be on-off on specific schedules or at the condition of the barcodes that exceed a specific value or finally by the user through a mobile app.
