We have this card in The Netherlands for 10 years now. Altough it is used in many ways, it's still no success. Even the government is advertising this card we call chipknip(electronic wallet). My bank even has given me a small device to lookup the credit on my card.
According to some researchreport it is not a success because (the dutch) people like to have the money in their pocket (the dutch are known for keeping their money in their pocket :-) ). The big advantage of this card should be that there is less money in the supermarkets, shops, gasstations etc... The other ease is that it is not nessecary to authenticate your code every time you pay with the card.
