QR Code Properties
Ignore Polarity
When checked, your device in trained state can read codes with polarity opposite to that of the code used for training.
Flexible Grid Size
When checked, your device in trained state can read codes with grid size slightly different (+/- one level) from that of the code used for training. That is, if you trained a 25x25 QR code, for example, with flexible grid size you will be able to decode 21x21 or 29x29 size codes, too.
Maximum Grid Size
Maximum Grid Size allows you to decode QR codes that are larger than size 49. You can either drag the slider or type in a specific code size to the text box on the right.
