I just signed up and I see a €5.00 charge on my credit card, what is it?

When you subscribe to Pcard Private, €5.00 will be charged to the bank card linked to your Pcard account.
This charge allows us to ensure, as soon as you subscribe, that your Pcard is correctly associated with your bank card. The amount is automatically credited to your Pcard account and this €5.00 credit will be used the first time you use your Pcard.
