Just some general information:
The European professional card (EPC) is available from 18 January 2016 for five professions (general care nurses, physiotherapists, pharmacists, real estate agents and mountain guides). It might be extended to other professions in the future.
General care nurses, pharmacists, physiotherapists, real estate agents and mountain guides can now pursue their professions more freely in other EU countries thanks to the European Professional Card (EPC). The card, available from today, aims to ease the free movement of these mobile professionals by simplifying the procedure for getting their professional qualifications recognised in another EU country.
I don't know if the sites you regged will be needed or if europa.eu is the only site that is needed to apply for a card. EuropeanProfessionalCard.com is a bit long IMO.
