Every day, PostNL hides a Golden Christmas Card on a PostNL postbox somewhere in the Netherlands. Anyone who is the first to find the postbox with the Golden Christmas Card, who scans the stamps on the postbox with the Chameleon eXplorer app and registers, has a chance of winning €500. This is how sending Christmas cards can bring you money!
From 10 to 16 December, between noon and midnight, PostNL gives a hint on Radio 538 and SlamFM six times about the location of the Golden Christmas Card on that particular day. Once the hints have been broadcast, they will also appear on the promotion page facebook.com/kaartwereld. After you have 'liked' the page, you will receive a notification automatically if a new hint is known. If the Golden Christmas Card is not found, it will be worth €1,000 on the next day.
The simple Chameleon eXplorer app works like a scanner. It can be downloaded for free via the Appstore and the Android Play store.
