A calling card
German design bureau Intertone in Hamburg created a Christmas card which makes a call when you open it. Intertone created the card for telecon provider O2 who used it for a special Christmas campaign. The card has an integrated sim card. After opening the card it dials a phone number which allows the recipient to make a real phone call with the Christmas card functioning as mobile phone. Patent is pending on this special card which combines new and old technology as well as human interaction.
