Currently, although used quite commonly, few people can distinguish between QR Code and Barcode. Below are some differences between them that you can refer to. Barcode
form : It is a linear barcode, a 1-dimensional code with lines and spaces of parallel width. QR code : Is a matrix barcode, a 2-dimensional code with interwoven rectangles, hexagons, dots and spaces. The device is scanned
Barcode requires specialized code scanning equipment to be able to read the information. QR codes are more favored when there are many software and devices that can read them. Just by using a Smartphone, you can read information from QR codes without spending a lot of other machinery or costs. Perhaps that is why the popularity of QR codes is almost overwhelming compared to other codes.
Fault Tolerance Fault tolerance
means that the code is susceptible to scratches, blurring, or loss of detail in the code. If the code is corrupted, scanning information may be affected.
In particular, the error tolerance ability of QR codes compared to bar codes is much superior. With fault tolerance from 7% - 30%, QR codes show their advantages and uses in business activities. In case the QR code is damaged, it can automatically fix the error and restore the data.
Barcode has the characteristic of accessing one-way data. Therefore, when the code is damaged, it is very difficult to repair.
Amount of encoded information
With nearly 7,000 characters of data that can be contained, QR Code provides users with the ability to store extremely large information. At the same time, not only characters, QR Codes can also attach images, domain links, etc. Thanks to that, many brands and businesses love and use QR Codes to promote information about their businesses.
Barcode can only contain 8-20 characters and is limited to two formats: Alphabet and numbers. If too much information is stored, the barcode size will also increase accordingly. Barcode information often stored is product description, price, item identification, etc.
Absolutely NO . QR codes are not an online information storage service. Instead, the data will be saved directly to the code image. Therefore, as long as the QR code image is intact, the information will be stored forever.
According to one of the world's largest companies providing cybersecurity and anti-virus services, the QR code generator software does not collect any personal information. The data it collects and displays to the code generator will include the number of times the code was scanned, the location, and the operating system of the scanning device. If a user registers an account at code scanning applications, the user's personal information will be stored at these applications.
Above is information related to what a QR Code is as well as how to create your own QR Code. Hope this article is useful to you. And if you want to use QR Code, you should consider the notes that TipsMake has shared with you.
