I’ve tried to read them from books, pens, … but it didn’t work. After some googling I’ve discovered that these barcodes need to be encoded by one of these two methods:

The Nokia N95 tries to scan and decode the encrypted image. You can encrypt up to 2,335 alpha-numeric characters with Datamatrix and 4,296 alpha-numeric characters with the QR Barcode matrix code. Unfortunately the Nokia N95 only supports messages with maximum 90 alpha-numeric characters.

Nokia 95 recognizes the decoded content as URIs, to which you can surf; numbers, to which you can call, or just plain text.
