An app which scans a QR code printed on receipts which leads to a direct json/table of the items purchased, location purchased, date, price paid.
NO PERSONAL DATA - just the item, store name & location, price, date, tax %.
People can CHOOSE to scan their receipt and have that data slurped into the app and uploaded to a national DB for price index.
sans QR system integrated to the sales we just need an OCR capable AI APP that you take a pic of the receipt and it parses it and tracks the prices.
An additional feature is just snapping pics of price tags into the app and it parses them, their barcodes, prices, location, etc...
Same as the Gas Price app-ish, but for any receipt as the header of every receipt has all the business information and a line item of price for purchases.
It would be great if we could require all sales to provide a QR code of every receipt which provides a json/table of the above (anon) data...
because I keep a running tally in my head for things that I buy and their prices.
