ACSI Card

I'm planning a 2 month tour of France starting in May and whilst using the foreign touring handbook I notice that members report if a site accepts camping cheques but not one site mentions if a site uses ACSI card. I know the club issue camping cheques so will have a vested interest. But this book is made up of reports by members for members so members should have the choice. Not all areas have sites that uses cheques.

Anyone have information on this.
