we operate an online store. we receive orders through ebay, and we print invoice with barcodes.
we also have the same barcodes on the items.
so i would like to write a software that does the following..
1- i scan the barcode on the invoice.
2- the screen shows me an image of what product i need and make model
3- i get the product and i scan the barcode on the product.
4- if it is the correct product it will show me a big green tick.
5- if it is the wrong product it will show me a big red cross.
