Hi. I bought one of these cards and got the password years ago. (An experience etched on my memory because it was mega hot, we didn't understand the (English!) instructions and had to be helped by fellow Brits and we had a dodgy mobile signal so couldn't receive the code they sent - we blocked the road for quite some time and rude words were said!) I've reluctantly tried to use it twice since, and failed both times. On both occasions the signs have said that parking for the day is about €6 but when I get to the "charge your card" screen, the minimum it asks for is double this. There doesn't seem to be an option to simply pay by credit card. Can anyone please explain!
