• The security thread is wider and the text "Norges Bank" is visible when the note is help up to the light. This is the same security thread that has been used in the other banknotes.
• For reasons of security, a number of small adjustments have been made in the printing, as was the case with previous upgrades. For example, there are a number of small circles on the front and reverse of the note.

Unlike the other notes, the 50-krone note will not have the holographic foil strip on the front of the note or the mother-of-pearl effect (a vertical strip of numbers that changes colour in the light) on the reverse of the banknote. The banknote will continue to have other security features such as the portrait watermark and the fluorescent print. We encourage the public to continue to use these features when controlling the authenticity of a banknote. A picture of the banknote may be found on Norges Bank's website, together with more details about the security features and about how to distinguish a counterfeit note from a genuine one.

The new 50-krone note will be put into circulation gradually from 1 February 2004. The current 50-krone notes will continue to be legal tender after this date and will circulate side-by-side with the new upgraded 50-krone notes.
