However, in order to remove legal barriers to market entry, it is necessary to establish a single licence for all providers of payment services which are not connected to taking deposits or issuing electronic money. It is appropriate, therefore, to introduce a new category of payment service providers, ‘payment institutions’, by providing for the authorisation, subject to a set of strict and comprehensive conditions, of legal persons outside the existing categories to provide payment services throughout the Community. Thus, the same conditions would apply Community-wide to such services.
