"Ginger Market" on the SJSU campus has attempted to use a similar "Just Walk Out" approach. It has not worked well. I've been double charged, charged for items I did not take, not charged for items I've taken, etc. The refund process was also a pain. It was so bad that they had to stop using it last spring, although they claim they are going to give it another go. Why even bother? Self checkout or a cashier work so much better and I have a hard time believing they are less expensive. The store is plastered with cameras. Seriously, there must be 100 cameras in the place. That's a lot of video to process, which has got to be costly, whether it is a machine or people who are reviewing it.
