What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that can store various types of data. Originally invented in 1994 by Denso Wave for the automotive industry, QR codes have become ubiquitous for storing URLs, contact information, WiFi credentials, and more.

Error Correction Levels

QR codes have built-in error correction that allows them to be read even when partially damaged:

• L (Low): 7% of data can be restored
• M (Medium): 15% of data can be restored
