Those Amazon just walk out stores like you’re describing are extremely expensive to setup though. Even a spall space requires tons of cameras and sensors, all items to be placed on shelves a certain way, lots of networking backend, etc. Most business are unable to do so right now and I’d say most buildings can’t accommodate it. My work looked into putting one of those in one of our spaces as a test and the cost/work to make it happen in even a small area of our business wasn’t worth it
