“The notes are going to have two security innovations in the satellite hologram and in the emerald number”, Bank of Portugal board director Hélder Rosalino told reporters.
He said that the new notes would be “extremely secure” because the European central Bank had been concerned with making them as forgery resistant as possible”.
The new notes are going to be slightly smaller than the current editions making them the same size as the €50 notes.
Hélder Rosalino stressed that there was “no need to change” old notes for new ones and they would “circulate simultaneously”.
The €500 notes are not going to be replaced and only those already in circulation will continue to exist.
