Qr example.

QR Code Explained. QR is a two-dimensional or matrix code that can encode up to 4,000 characters or 7,000 digits. The code is easily recognized by the characteristic three finder patterns in the corners of the symbol: Those patterns are quite large, so the code needs more space than other 2D symbologies, at least with small amounts of data.

The optimal scanning distance from a QR code is a 10:1 ratio of distance to width. For example, if the QR code is 2” wide, the optimal scanning distance is 20” away. QR codes are good at accommodating scanning distances near the optimal ratio, though. Scan the QR code to test its functionality at—and near—the 10:1 distance ratio.1. Rayleigh Quotient.
