Why are there bar codes on everything at the grocery store?
Why are there bar codes on everything at the grocery store?
Is it inventory? Or is it for security? If the bar codes don’t set off the burglar alarm things by the doors, then what does? I’ve never known all these years why they have those pillars by the doors, or why the have barcodes.
Best answer:
They don’t set off security, but it makes it easier to check out when you can quickly scan your items. Produce, like tomatoes and corn, don’t usually have bar codes.

they just scan those at the checkout instead of manually putting price tags on everything and punching them in at the registers.
Little trivia for you: the scanner that reads the bar code is reading the white bars not the black. The laser is reflected off the white.

Bar codes are mostly for inventory control and check out. Sensitized metal strips hidden in merchandise are used for the alarms.

Bar codes are simply a unique number that can identify a product. This number can be used for invertory control and as a method of pricing at the checkout counter. This saves the store from having to put a price tag on all their products. Bar codes are not for security.
The pillars by the door are sensor for the security strips put in a lot of merchandise. They will alert the store if a product with a secrity strip that hasn’t been deactivated passes between them.
There is no connection between the bar code and the security strip.
