Seems complicated. Even if you're resetting tare on the bin regularly, fruits and vegetables can have significant changes in weight due to dehydration, and most markets are doing things like misting chilled produce with water, which will introduce constant and somewhat unpredictable changes in bin weight.

The tare would be reset each time a customer picks something up. The total bin weight doesn’t matter, just the delta between before and after the computer vision system identifies that a customer removed some of the bin’s contents.

This would run afoul of commerce laws in pretty much every US state. Tare must be set from zero, not relative to whatever happens to be on the scale, and certainly not on the fly.
