What type of barcode should I choose?

The simplest and least expensive method is necessarily the use of barcodes. But it is still necessary to choose the type of barcode that best suits our needs.

One-dimensional barcodes / UPC: How do they work?

The UPC barcode is the one you see on most products, as it is the most widely used digital identification system in the world. Most stores and grocery stores use this system to scan products at checkout.
It is composed of a series of black bars and spaces of different thicknesses. Under the barcode, a coded number identifies the item in a unique way.

Pros:

• It can be used on a thin round item like a cable
• The most used barcode

Cons:

• It can only be scanned horizontally
• It can take up ten times more space than a QR code when printed
• It can only store alphanumeric data

QR Code or two-dimensional barcode: Definition

The QR barcode is starting to be used more and more thanks to the introduction of smartphones and because of the current pandemic. We can see it everywhere on the table at the restaurant to display the menu on the phone or on advertising posters to refer to the website of a company.

It is a square shaped barcode and is composed of several small black and white squares. It can store a lot of information such as brand name, model number, maintenance records and many other details. They provide a hundred times more data than a regular barcode.

Pros:

• It can be read horizontally and vertically
• It can contain more information than a standard barcode.
• It can be read by smartphones with a camera (easy to use).
• It contains a corrective code that allows to work if a part of the code is torn and dirty thanks to the information redundancy (error margin from 7 to 30%).

Cons:

• Cannot be used on a thin round item like a cable.

No matter what type of barcode you choose, it will allow you to track material faster while reducing the risk of error.
