How to Scan or Use a QR Code?
A QR code is a 2D matrix that contains information that can be accessed by a Smartphone or QR code scanner. QR codes contain information in both the horizontal and vertical dimensions, so they can hold more data than barcodes.
History and Development
Toyo Denso, a member of the Toyota Group, developed QR codes in 1994 to keep track of auto parts being manufactured. In the beginning, they were popular because of their high storage capacity. They also made it easy to read. As the years pass, QR codes are no longer confined to the industrial and factory sector. We can see their usage in many aspects of our daily lives.
The Importance of Relevance and Importance Today
With the increased use of the Internet, QR codes have become more valuable than ever. QR codes create a link between the real and virtual worlds. Users don’t have to waste time looking for websites, services, or information – they can simply scan the code. These devices are also portable and effective, making them useful in a variety of industries, including retailing, teaching, health and marketing.
Understanding QR Codes
What is a QR Code?
A QR code is a matrix barcode containing information encoded into a square-shaped black and white grid. It could be anything, from the URL or contact information to product details and payment information.
What is QR code?
A QR code can be read by a device with the ability to read the data stored as a grid pattern. The device’s camera captures an image of the QR codes, which is then processed by software. As mentioned above, this process is completed in a blink of an eye and gives instant access to encoded material.
Types of QR codes
Static QR Codes
QR codes that are referred to as static indicate the fact that once they have been created, the data represented by them cannot be changed. These codes are best suited for basic input such as a URL or a phone number and name.
Dynamic QR codes
Dynamic QR codes are those QR codes where the data can be edited or updated without having to change the code. They are therefore ideal for applications where data changes frequently, such as information about events or promotional activities.
Technical Specifications
QR Code Structure
There are also other components of the QR code standard, including the finder pattern, which is composed by 3 squares with 4 terminating rectangles, the alignment pattern, which is a 5 square pattern, the timing pattern, version information, format information, and finally the data. These two components ensure that QR codes can be read quickly and easily.
Coding Data in QR Codes
The QR code can contain a variety of data, including numeric, alphanumeric and binary data, as well as Kanji. The type of data determines the amount of information that can be stored.
QR Code Sizes and Versions
QR codes are available in two main variations, with 38 different types that differ in their layout and carry different amounts of data. The number of digits indicates the amount of information that can be stored within a QR code. The higher the version the more data it has.
Error Correction Levels
QR codes are designed with redundancy for error correction, so that they can still be read even if a portion of the graphics is damaged. There are four levels of error correction: Low (L), Medium (M), Quartile (Q) and High. The QR code can be read more easily with successful error correction, but the information stored in the code is reduced.
