QR coding is a pretty useful invention, and has plenty of applications but I personally never thought one would embrace technology to the point of imprinting them onto the back of a coin. Behold, the Royal Dutch Mint has produced what is the world's first QR-coded coin to celebrate the 100th anniversary of the mint in Utrecht.

The coins will be limited-edition and will be produced in silver as well as gold. The silver 5€ and gold 10€ will be issued on June 22, 2011. The QR code scans � http://www.q5g.nl.
