We all know it, we all use it: when you want to obtain information about a product or want to scan a barcode to find out more about it. For this, there are bar code scanners that allow us to do this as if it were a magic wand. But how do they work? What is the technology behind them? And, above all, how can you make your own?
To understand how a bar code scanner works, we must first know what the bar code is. This is a sequence of lines and opposite angles that contains information that can be read by a machine. This type of code has its origin in the scientific revolution and dates from the year 1948. In fact, this type of code revolutionized the way in which we can classify products.
As for how these scanners work, they make it possible to read these codes by magnifying them and filming them with a camera sensor. With this sensor, its processor or CPU processes the image and recognizes the symbols that compose it. Then, by means of an integrated sensor, the scanner emits an electromagnetic impulse that activates the device, so that on its screen you can see what you are scanning.
In order to learn how to make your own scanner of codes you can use APIs or creation tools that will allow you to create different types of applications using this type of recognition system.
APIs are interfaces that allow information to be transmitted from one platform to another. Thus, if you have an application developed on iOS or Android platform you can incorporate into it the functionalities offered by an API without having to develop one from scratch for each platform. In addition, APIs simplify the programming of several functionalities at once.
In this case we will focus on Barcode Generator APIs that have appeared recently on the market and have revolutionized the way in which companies and individuals generate their codes.
Barcode Generation API is one of those that you should try out today. It has a wide range of different types of codes, such as QR codes, EAN codes, or even UPC or ISBN codes. In addition, it works in several programming languages and is very simple to use.You will only need your personal API key and you will be able to access information and generate any code at any time simply by uploading the URL link to which you want your code engraved or even just typing it in manually! And you can create it instantly by using one of these three options:Using
Generate over 30 types of barcodes on the fly quickly and use in your application.
To make use of it, you must first:
1- Go to Bar Code Generator API and simply click on the button “Subscribe for free” to start using the API.
2- After signing up in Zyla API Hub, you’ll be given your personal API key. Using this one-of-a-kind combination of numbers and letters, you’ll be able to use, connect, and manage APIs!
3- Employ the different API endpoints depending on what you are looking for.
4- Once you meet your needed endpoint, make the API call by pressing the button “run” and see the results on your screen.
