We should replace #BarCode on products with #QRCode as #QRCode needs no specialised hardware to be scanned & can be scanned via camera.

By the spec a QR code keeps a quiet zone four modules wide on every side. Readers forgive most of it: zxing-cpp's finder check accepts almost none, and it read this code with a dark frame 4, 2 and 1 modules away. Touching, no read: the frame merges with the finder's outer ring.

#QRCode #Design

A QR code printed light on dark is allowed by the format, and a reader that assumes dark on light misses it. zxing-cpp keeps tryInvert on by default: when the first pass finds nothing it inverts the image and retries. The same code both ways, decoded with the option on and off.

#QRCode #Android

How a scanner finds a QR code: any row through one of the three big squares runs dark, light, dark, light, dark in 1:1:3:1:1, any size or tilt. Count run lengths along the rows, keep where five fit the ratio, check the column. One row of my test code: 12, 12, 36, 12, 12 px.
