How a barcode is generated?

Barcodes are generated using software. Stores decide what information (quantity, color, type) they want to collect with the barcode and choose the barcode format. The software will automatically generate a machine-readable barcode.

If you want to create custom barcodes that let you determine your own symbology and product numbers, you can do this on your computer with software, a scanner, and a label maker.

When to use custom barcodes

The perks of going the custom route include affordability and more flexibility with product numbering. You can get creative with the way you break down the digits into subcategories like product types and other classifiers.

By going custom, you create your own barcode format and point it to internal data you manage. In this way, it works similarly to a SKU (more on that later).

Once you’ve defined your barcode, you can begin printing and labeling your products. You can scan the barcodes into your point-of-sale system and attach them to products in your inventory management system. If your POS has a barcode generation app, like Shopify POS does, then the entire process can be done from there.

How does reading a barcode work?

Barcode scanners can be connected to a computer through a serial port, keyboard port or interface device called a wedge. A barcode reader works by directing a beam of light across the barcode and measuring the amount and pattern of the light that is reflected.

The scanner converts the light energy into electrical energy, which is then converted into data by the decoder and forwarded to a computer.

What are the advantages of barcode readers?

Barcode readers offer several advantages in retail environments:

· reduced pricing errors

· increased accuracy and efficiency

· improved customer service

· reduced inventory levels

How data is stored in a barcode?

As we know that a barcode is a square or rectangular image consisting of a series of parallel black lines and white spaces. The information is encoded between the length of each shaded line and the space between them.

A scanning device uses a laser to "read" the bar code by scanning in the unique bar of shaded lines. A barcode scanner reads the lines from left to right.

A barcode scanner reads pattern of black and white bars which turns the information in the binary code (0 or 1). Computer reads the information in the binary forms only and same is displayed on the screen of the monitor.

The "number" written in the right hand side of the "center guard" informs about the type of the product whether it is made of plastic or by natural things, vegetarian or non-vegetarian.

In the picture given below, If “2” is written instead of 0; it shows that the product is either vegan or non-vegan.

Two digits near the left bar i.e. 0 and 5 inform that the product if either made in USA or in Canada because barcode from 00 to 13 is assigned to these two countries.

The last digit "7" given on the right hand side of the barcode is a check number, which ensures that whether information has been properly read by the barcode reader or not.
