What is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that can store data as black squares and white spaces. It can be read by a smartphone or dedicated QR code scanner.

How does a QR Code work?

- Encoding: The data is encoded into binary bits and divided into small modules.
- Arrangement: The modules are arranged in a square grid, with black modules representing bits and white modules representing zeros.
- Location Patterns: Three distinctive location patterns are placed at the corners to help the reader locate and orient the code.
- Alignment Patterns: Smaller patterns within the code allow for corrections in case of slight distortions.
- Timing Patterns: Grid lines help the reader track the position and size of the modules.

Types of QR Codes

- Numeric: Stores only numeric data.
- Alphanumeric: Stores both numbers and letters.
- Byte: Stores binary data, including images and text in any language.
