The Robustness and Error-Correction of QR Codes: How They Work
Modern life cannot be imagined without...
The Advantages and Disadvantages of QR Codes: An Overview
QR codes (Quick Response codes) are today one of the most used tools in the digital world, connecting the physical with the digital. They are used in marketing, payments, logistics and other industries.
Procedure for Decoding a QR Code
Decoding data from the QR code is the reverse of the encoding procedure.
Procedure for Generation/Encoding of a QR Code
In order to convert input data into a QR code symbol, we’ll go through some step
Structure Of A QR Code
Each QR Code symbol shall be built of square modules arranged in a regular square array and shall consist of function patterns and encoding region. And the whole symbol shall be surrounded on all four sides by a quiet zone border.
QR Code Error-Correction
The QR code achieves powerful error-correction capability by using Reed-Solomon codes.
Information Capacity and Versions of the QR Code
Each QR Code symbol version has the maximum data capacity, according to the amount of data, character type and error correction level.
