I have been thinking about this one a bit more. I believe the idea is to remove various sources of friction in the system. You may be able to get away with not scanning. Again, pretend the store has a system to send you the grocery bill in a processable electronic form. The assumption is most stuff is purchased from a large supermarket. Typically stuff like lot numbers, expiry, best before are know so those could be included. This information could be included into something like Google Calendar and reminders set out. Imagine someone has Amazon Alexa (was "listening to Too Embarrassed to Ask" podcast about Alexa). It would ask questions about the food: "you bought Arugula two days ago? Have you used it yet?" Privacy aside, this may be much more usable.

I do like the way you are looking at the problem, but as high overview it's all down to supermarket to provide this information (if they got it and easy to share).

I was hoping to find kinda open data date for grocery food but still looking for.

Hope get more people interested on the idea so it gives me a push to explore more paths to solve the problem.
