I have a subscription on my Pcard+. How does it work?

Your subscription gives you access to one or more car parks according to a fixed price. When you visit one of these car parks, obviously you do not pay anything. If you use your Pcard+ in a car park for which you do not have a subscription, you pay the rate which applies to this car park reduced by all the promotions that you benefit from as a Pcard+ holder.
