We certainly often go shopping at minimarkets, supermarkets or modern shops. When making a payment at the cashier, the cashier can easily input the price of the goods we buy.
With a scanner that emits a laser beam, the officer only needs to point to an image in the form of a collection of thick and thin lines on the packaging of the products we buy. Automatically all information about the item including the price is directly inputted into the cashier’s computer.
Well, that line drawing is called a barcode, or bar code.
How to make a barcode on a cellphone

This barcode generator was chosen because in addition to getting the highest rating, its size is also small so it will not burden your cellphone. Barcode also has a simple and easy to understand interface.
2. Run the Barcode Generator Application
After the installation process is complete, open the application and select or press the + sign in the red circle. Then select ADD CODE.
3. Select the Barcode Type
Then complete the information data that will be included in the barcode.
4. Barcode Image Ready to Save
You can save the finished barcode image in jpg or png format. In addition, you can also directly share the finished barcode to whatsapp, line, facebook, or other applications.
How to Create a Barcode on a Laptop/PC
Furthermore, you can also create barcodes on your laptop or PC easily too. Not only ordinary barcodes, you can also make other types such as QR Code, Code 39, Code 128, and so on.
There are many online garage generator services that you can use. In this example, we use barcode-generator.org.
The method is as follows.
- Go to www.barcode-generator.org
- Next, please select the type of barcode you want to create in the menu CreateFree:
- Next, please provide the required data for the barcode you want to create.
- Finally, please click the Create QR Code button.
- Finished.
The barcode you create can be downloaded in JPG, EPS, or SVG format.
Understanding Barcodes
Barcode itself means a collection of optical data that can be read by a machine. In a barcode there is a collection of data which is symbolized by the width of the line, parallel line spacing.
Barcodes are also often referred to as barcodes, linear or one-dimensional symbology.
Actually, apart from being a line, barcodes also have the shape of a square, point, hexagon or other geometric shapes that contain a matrix code or two-dimensional symbology.
Types of Barcodes
In general, the types of barcodes that we can easily find in everyday life around us are two, namely 1-dimensional barcodes and 2-dimensional barcodes.
1. 1 Dimensional Barcode
One-dimensional barcodes are also known as linear codes. One-dimensional barcodes we often see are found on product packaging that we buy from minimarkets, supermarkets or other modern stores.
1-dimensional barcode itself also consists of several kinds including:
- Code 39, are alphanumeric barcodes that vary in line length. Generally, barcode code 39 is often found in inventory, asset tracking and identification cards.
- Code 128, is a very high density alphanumeric barcode with varying line lengths. Generally, barcode type code 128 can be found in shipping control systems and warehouse management systems.
- Interleaved 2 of 5, are numeric barcodes that vary in line length. Generally, we can find 2 of 5 interleaved barcodes in industrial and laboratory sectors.
- Universal Product Code or UPC, is a numeric barcode that has a fixed line length. Generally, we can find UPC barcodes on small product labels.
2. 2 Dimensional Barcode
2-dimensional barcodes have their own advantages when compared to 1-dimensional barcodes. 2-dimensional barcodes can contain many digits of characters up to hundreds more.
In addition, the appearance of a 2-dimensional barcode is different from a 1-dimensional barcode or linear code. The data in a large 2-dimensional barcode can be stored in a small space.

The use of 2-dimensional barcodes in today’s daily life can be found in manufacturing companies.
Its use is starting to be widely used because it is more efficient, when compared to 1-dimensional barcodes, it is smaller in size but can store much more information data.
It’s just that the price of a 2-dimensional barcode reader is still relatively expensive when compared to a 1-dimensional barcode reader.
Well, those are the steps on how to make a barcode on an Android cellphone easily and quickly. Good luck.
