The European Central Bank (ECB) introduced Monday new €100 and €200 banknotes that are to enter into circulation on May 28, 2019.
"The new €100 and €200 banknotes make use of new and innovative security features," the ECB said in a statement.
According to the ECB, the new notes are easy to check with feel, look and tilt method -- like the old denominations.
"At the top of the silvery stripe a satellite hologram shows small € symbols that move around the number and become clearer under direct light," it said.
"The new €100 and €200 banknotes also feature an enhanced emerald number," it said.
"While the emerald number itself is present on all the other notes of the Europa series, this enhanced version also shows € symbols inside the numerals."
"Both denominations are now the same height as the €50 banknote," the ECB said. "However, their length remains unchanged -- the longer the note, the higher the value."
