All of the places around here that had first-gen units with a scale on the packing side (to make sure you actually scanned eg a banana and not a two pound block of cheese, yet were constantly wrong) have replaced them with newer versions that don't have scales or any other way that I can see to validate that what you scanned is what you put into your bag.

I'm not sure where I would find the data to back this up, but since it seems like an across-the-board change I imagine the labor savings have proven to outweigh (heh) the inventory shrinkage.

To me, the Uniqlo system where everything has an RFID tag and the machine just automatically scans the contents of your basket is the platonic ideal but I know that comes with issues of its own in different retail contexts.
