We can see bar codes in every grocery items we buy. A symbol bar code is made of lines and spaces, all of which are made up of symbols. When industries and companies apply for symbol bar code, there is a certain code that they follow. Out of the different codes different companies use, one company chooses one code and follows through that code.

Consumers don’t understand bar codes. What we do understand, however, is that cashiers always place the symbol bar code to a symbol bar code scanner. Hence, the price of the list item is automatically encoded into the cash register.

Companies use bar codes to provide them with fast and accurate encoding of data onto their computers. It is then easier to compute for inventories. It will also be easier to look for data in case they need some important information about their products and sales. It is also more accurate than manual data entry. Human errors are eliminated when using a symbol bar code.

In every bar code, there is a check digit. When a symbol bar code scanner scans the symbol bar code, it also computes for the check digit. If the check digit did not match, the machine that reads the symbol bar code would automatically ask for a rescanning of the item. It is because it has detected an error in its scanning.

Bar code readers read bar codes that are printed on the products. Bar code readers are made up of bar code scanners, decoders, and cables that are attached to a computer. A symbol bar code helps companies save money. This is because companies do not need to hire additional employees just to do the inventory. By using a symbol bar code, inventories and data checking are automatically encoded into the computer system. There will be no more manual encoding of data which is more inefficient and time consuming.
