The aim is to provide a system that enables a protected replacement of card, a management of fractions of parking units and a management of the change returned by the system, for uses in one of more local authority areas. The disclosed system is of the type comprising a memory card, a box for the reception of the card comprising a memory, wherein the storage capacity of the management memory of the box is limited to a maximum number of pre-determined parking units, and wherein transfer means provide for the transfer of the balance of parking units contained in the card towards the management memory of the box when the arithmetical total of the number of added-up units of the card balance and of the current content of the management memory of the box is smaller than or equal to the capacity of the management memory.
