What "cost effective" method will be used to ensure that everything in the shopping cart has been scanned?

:\

I remember my local Safeway (before being rebranded to another chain) testing out handheld barcode scanners used in effectively the same way a number of years ago. Users of the system would occasionally be asked to have their items rescanned through a checkout to make sure everything went through correctly. It could be that they will employ a similar "loss prevention" system.

The system was eventually ripped out due to shopper confusion and massive amounts of theft. Rarely anyone ended up using it. It was shortly after replaced by self-scan checkouts with a member of staff monitoring a bank of them.

Costco has people at the exit who check the contents of your cart against the items on your receipt. You could have a check-out/verification/de-magnetization lane specifically for people who use this service; yes, it's still a line, but it would move much faster than a typical check-out line, since the payment process is removed.

Great, let's eliminate more of the lowest paying jobs in America, so those folks can move up to... unemployment. Here's hoping the experiment fails.
