(2)Union standardised terminology for the services that are common to at least a majority of Member States should be established. Some Member States have included in their provisional list of most representative services different variations of the same service.

In order to identify the broadest possible number of the most common services within the Union, while at the same time ensuring that the services' terminology is harmonised at an adequate level in order to enable the consumers to understand and compare payment account fees and offers on a cross-border basis, the core elements of services should be taken into account.
