20/8 Editions Underbahn Books with QR Codes

You can take a picture of the QR Code and send it via MMS to their server. There it is decoded. Naturally you can also directly read it with this QR Code reader and send them an SMS (they could also encode the SMS right away - here is the result with my long message). It's cheaper and I guess they will be surprised;)
They promise to send you back an answer in 24 hrs. and give you an URL to access the bonus to your book.
