Like bar code, QR code is trendy today in terms of adding links to websites. Hyperlinks in web pages that link to a website, such codes in the physical world, are also known as hard links. Therefore, the QR code is called the 'hyperlink in the physical world.' This code, which can be found anywhere on a book or a wall, can be scanned on a QR reader as well as a smartphone and read.

Turn it up
QR code (QR-Quick Response) technology was invented in 1994 by a Japanese company called Denzo Wave. Denzo Wave was designed as a tactic to count auto parts accurately. To this day, Denso Wave holds the patent for QR code technology.
Technology
The difference here is not only the ease of reading but also the average barcode. A barcode can hold up to 20 digits, but QR codes can hold up to 100 times that amount of information. It can also include pictures in addition to text. It can store are over Seven thousand eighty-nine numbers and 4296 letters. It's a massive amount of data.
QR codes store data in their modules. The information thus retained is interpreted by a special algorithm in the software that reads it. This takes very little time. This is why they are called (QR) codes. Also, when reading something like a smartphone, you do not have to read exactly one. QR codes can be read even in the slightest.
A QR code is square. It has three squares, one at each of the three corners. These are called eyes. The other end is smaller than the original court. There is also a dotted line connecting these three ends. The dot pattern in the area covered by them represents the relevant message.

New generation
Although Denso View holds the patent, anyone is allowed to develop this technology. Accordingly, different types of QR codes have now emerged.
* Smaller than standard QR codes, there is a way to hold less data (35 digits). It is called Micro QR Code.
* I QR code is a small but large data storage model. It has 422 horizontal and vertical modules. It can hold up to 40,000 digits.
* The data in a QR code can be read by anyone, but the unreadable form is called SCQR (Secure QR code). They require specialized software and a reader to read them.
* Frame QR code is a type of data that can be printed with a small image in addition to data.
* Animated QR codes are now more advanced than standard QR codes.
Benefits
In addition to adding links to websites, QR codes have various benefits. These can be used to keep the details of various products in a small space. Therefore, its packaging is not a barrier to retaining product details. By using this method when publishing newspaper advertisements, more data can be stored in less space.
