Requires fixed barcode length

[designosis]

This appears to only work with fixed barcode lengths assigned to characterCount, and therefore is useless for QR codes.

Any thoughts on a fix?

Well, a QR code is not a barcode. A barcode is numerical and fixed length, while qr-code is alpha-numeric and can contain any sort of information of any length. Therefore it is pretty impossible to automatically recognise a string to originate from a qr code.

The best thing you can do is implement a regex specifically for the data format you expect to be in your QR code.
