Edible QR-codes
German biscuit manufacturer Qkies has developed a new application of QR-codes. The codes are printed on edible cookie dough, so everyone can send a message on their self baked biscuits. A package contains dough for 20 cookies and 20 edible QR-codes which can be scanned with a smartphone. The edible code can link to a website or for example a YouTube video. The mix of Qkies can be ordered online at www.qkies.de.
