What is a QR Code?

A QR Code (Quick Response Code) is a two-dimensional barcode that stores data in square grid patterns. When scanned by a smartphone or QR scanner, the code instantly decodes the information, such as URLs, text, contact information, or WiFi details. QR codes are superior to traditional barcodes because they can store more complex data, including multi-format information, and support error correction to remain scannable even when partially damaged.

A Short History of QR Codes

QR codes were first developed in 1994 by the Japanese company Denso Wave to track vehicles during manufacturing. Over time, their use expanded beyond industrial purposes to advertising, logistics, ticketing systems, menu cards, healthcare, payments, and many other industries.

Types of QR Codes

There are two main types of QR codes:

Static QR Codes

How Does a QR Code Work?
