500-krone note - security features

All Norwegian banknotes are printed in intaglio on cotton paper. This gives them a special "feel" which distinguishes them from copies on ordinary paper. If you notice that a note "feels" different when you receive it, it is important that you carry out some extra tests.

Holographic foil strip

Like the 100-krone, 200-krone and 1000-krone notes, the 500-krone note has a holographic foil strip with the image of a Norse horse and the value of the banknote to the right of the portrait. When you tilt the banknote, you can see the play of colours in the motif on the holographic foil strip.

Watermark and security thread

The banknote contains a portrait of Sigrid Undset. When the banknote is held up to the light, the watermark, a portrait of Sigrid Undset, and the security thread are clearly visible. The watermark, a single portrait identical to the main portrait, emerges in dark various shades of brown. On the new banknotes, you can feel a variation in the thickness of the paper along the watermark. When the banknote is held up to the light, you can see the security thread with the text NORGES BANK.

Iridescent effect

The reverse of the banknote features a vertical strip consisting of the number 500 written horizontally and repeatedly. If you tilt the note, the numbers change colour. This is called iridescent effect.

Rosette with a hidden "N" and microlettering

If you study the banknote very carefully, you will also discover microlettering, and in the rosette, the letter "N" will emerge when the banknote is held up to the light at an angle. Microlettering appears on the front and reverse of the banknote.

Register mark

There is also a see-through register mark to the right of the portrait. When the banknote is held up to the light, the non-coloured portion of the register mark on the obverse is filled by the coloured portion of the symmetrical mark on the reverse, thus forming a complete register mark.

Fluorescent print

When the banknote is exposed to ultraviolet light, part of the print as well as small fibres in the paper become fluorescent.

There is an invisible flower to the left of the portrait which is only visible when the note is exposed to ultraviolet light. A narrow strip on both sides of the holographic foil strip will also light up.
