EPCI was established in 1998 as a a certification institute for Bancontact/MisterCash (BC/MC) & Proton terminals that implemented specific BC/MC & Proton terminal specifications published as of 1999.

While the original mandate for EPCI came from the issuers of BC/MC cards, EPCI started to operate a terminal certification for additional specification that were instrumental for a group of acquirers, with an initial focus on credit cards.  The motivation was straightforward: many terminals accepted both the BC/MC or Proton cards next to credit cards. In addition credit card terminals needed to provide seamless interoperability with multiple acquirers.
As of 2001, multiple terminal specifications were certified for this domain of activity:
  • ATEA on-line (discontinued in 2010)
  • ATEA semi-off-line (discontinued in 2010)
  • A specific Europabank specification (discontinued in 2003)
  • C-TAP (Belgian version - on-line and semi-off-line)
Given the international success of C-TAP, it was decided in 2010 to consolidate the C-TAP specification in Acquiris. The transfer was organised in 2011.
