Retail POS System is one that is very useful for stores. Usually, it comes with receipt printers, bar code scanners, magnetic stripe readers, and cash drawers.
I am going beyond the concept. Could it be possible someday to have a system that detects shop lifters and crooks? I mean, it would be a great invention to have. If a system could spot a person that could scan a person in queue with his loot hidden in his garments, how cool would that be?
Thinking, would that invention be very costly? But that would be worth the penny, wouldn’t it?
