Whenever I return from grocery shopping, my first instinct is to throw it all in the fridge as fast as possible so I can continue with whatever it was I was doing before I left.

However, I am very guilty of buying too many fruits and salad mixes and letting them expire before eating them.

If I were to get into the habit of actually scanning everything I buy before storing it, how would this work? Would I scan a UPC? Would some sort of image recognition tell what I scanned and assign it an arbitrary expiration date?

I like the idea, but I'm wary of spending time scanning everything.
