Bill's App

There is a lot of paper wasted at receipt in supermarkets while most of the receipts are thrown away directly after completing the transaction.

An app that makes it so that you don't have to waste the paper you can scan an NFC tag and the bill is added to the app and you can search for the things that you bought. To cut down on waste by making an app that allowes you to scan a code at the supermarket anywhere that you need a bill to store it on your phone, thus receipts become obsolete.
