Key security features
There are two key public security features which can be checked to help confirm the note is genuine:
A metallic hologram which changes between the words “Fifty” and “Pounds” when the note is tilted.
A large see-through window with a gold and green foil on the front depicting a finely detailed metallic microchip image.
All Bank of England polymer notes are designed so one can check the holographic image switch and see through window as an easy and recognisable means of confirmation.
