Far better would be something like:
- Go to grocery store
- Photograph the shelves in PriceHive app
- AI scans the images, detecting products and reading prices from the price tags
- Each is stored into a database as a price on a good at a location at a timestamp
After data pool is established from many users (or even just one):
- Go to grocery store
- Open PriceHive app
- Hold a product in the viewfinder
- AI identifies product
- app shows price history across time/locations
That kind of shit needs to be built. Government will probably find some way to make it illegal, but whatever.
