A QR code (Quick Response code) is a type of matrix barcode that stores information as black and white patterns. It can be scanned by smartphones and QR readers to quickly access URLs, text, or other data.

Error correction determines how much of the QR code can be damaged or obscured while still being readable. Low (7%), Medium (15%), Quartile (25%), and High (30%) — higher levels allow for partially covered QR codes.

For most use cases, 300px is ideal. Use 200px for small inline uses, 400px for posters, and 500px for large prints or billboards.

Question 4

Can I encode a URL in a QR code?
