Many EU Member States, and some non-European countries have established eID services, which produce slightly different authentication tokens. In addition, industrial standardization activities have produced many different standards. The IdMS will be able to consume a broad variety of such authentication tokens, work with a broad variety of mobile identification services and transform them into a standardized, interoperable and secure format. The choice of this standardized format will be based on industry best practices, and on the forthcoming eIDAS interoperability framework (eIDAS -Interoperability Architecture, 2015). Moreover, the IdMS will be able to directly communicate with a selection of European and non-European eID services.
