I happen to know something about QR Code, so might shed some light here. There are all together 40 versions of QR Code, each with a pre-defined size to encode a certain maximum data. To encode the longest data, you can select a Version 40 QR Code, which can encode

maximumly 7089 numeric data, or 4296 alphanumeric data. You can also lower your error correction level when creating QR Code, that way even more data can be encoded. But keep in mind that too low an ECL might cause you the accuracy of your barcode image.
