What are QR Codes?
QR codes (Quick Response codes) are two-dimensional barcodes that can store text, URLs, contact info, Wi-Fi credentials, and more. They were invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous in everyday life.
Error correction allows QR codes to remain scannable even when partially damaged or obscured. Higher levels store more redundancy but require a denser (larger) code for the same data.
