S-Bonuscard is in the wallet of 1.8 million Finns; which is a lot in a country of 5.3 million people. They use it in the thousands of stores and restaurants of the S Chain, mainly to get bonuses and discounts. This campaign promotes a lesser known feature: the card can also be used as a credit card. Despite being such a popular card and having many uses, this is the first known case of using the card as a musical instrument and a sound effect tool.
