Chloe Shen watched as Stephen Su finished scanning and the checkout screen popped up on the screen. Then he took out his phone to pay and took her out of the supermarket. They were unimpeded along the way and no one checked...
She was a little puzzled: "If someone deliberately missed one or two bags with the machine, or just left it without scanning, wouldn't no one be able to find out?"
"Didn't you see that there are a bunch of cameras around? They are all monitoring, and there are access control systems at the exits. If any goods are detected that have not been paid for by scanning the code, the alarm will go off." Stephen Su explained casually and stuffed several bags of potato chips into her hands.
"...Actually, although that's what I said, there's no one supervising this thing after all. When there are a lot of people around, it's hard to prevent them from sneaking out in troubled waters." He thought for a moment and added.
In fact, we often see online that some netizens have experienced that after completing self-service checkout and returning home, they found that there were still a few items they had not scanned.
