The national postal company of the Netherlands, PostNL, launched a special postage stamp for the Broadway sensation, Jersey Boys. By using our Cee Platform, an invisible Chameleon Code was added to the stamps and when scanned with our Cee App users will be directly linked to a special video of the Jersey Boys. On top of that, users will be linked to the official ticketshop  and are given the possibility to directly purchase musical tickets with an amazing discount. A great way of promoting an event that, with the help of analytic tools will also offer insight to the behavior of the end users.
