A QR (Quick Response) code is a two-dimensional barcode that encodes data as a pattern of black and white squares. Smartphones can scan and act on QR codes instantly — opening URLs, connecting to Wi-Fi, or dialing phone numbers. A single QR code can encode up to 4,296 alphanumeric characters.

Level M (15% correction) works for most use cases. Level H (30%) is useful when you want to overlay a logo in the center of the QR code.
At least 2 cm × 2 cm (about 0.8 inches) for reliable scanning at close range. For signage or posters viewed from a distance, scale up proportionally — at 1 meter scanning distance, use at least 10 cm × 10 cm.
