QR Code Capacity per Version/Error Correction

Postby Tim Van on Mon Jan 23, 2012 1:09 pm

Looking at the QR Code SDK for purchase.
I need to produce QR codes with alpha-numeric input strings. Do you have a chart that lists the maximum limit of alpha-numeric input characters on a version and error level basis?

Thank you for the interest on our software. You can find the chart in QRCode Specification. The excerpt is attached.

Note that the alpha-numeric character set in QR Code does not include capital letter. It includes 10 digits, capital letters A-Z and 9 symbols.

Our encoder increases the version if it finds that the version specified is too small to encode the data. See http://mdn.morovia.com/manuals/qrcode-f ... php#N10723.
