QR Code with multiple information type

Question

I was wondering if there's a way to build a QR code with two kinds of data - one text data and two link URLs. Is it possible to do it?

Answer 1

A QR Code is a two-dimensional barcode capable of storing (according to Wikipedia) up to 2,953 bytes of binary data or 4,296 simple alphanumeric characters. The data can contain whatever you like.

The difficulty with storing multiple URLs in a QR-code is not that it is impossible, but that most scanner apps in smart phones and so on will only process a single URL. If you are writing the scanner app too then, yes, it it possible, otherwise it is possible but probably not advisable.

If you wish to store a single URL and some contact details you might look at storing a vCard in your QR code (here is a generator; I have no affiliation with this project).
