Security features

Swedish banknotes are sometimes counterfeited, even if this is very unusual. Swedish banknotes have advanced security features, so that they are difficult to counterfeit and it is easy to check whether they are genuine.

When you check a banknote, you should examine a combination of several security details.

Security strip

Denominations 1,000, 500, 200 and 100

The banknote has a vertical security strip with three windows. The windows feature images that move and alternate motif between "KR" and a royal crown when the banknote is tilted. The security strip is placed to the left of the portrait on the obverse of the banknote. The placement of the security strip may vary by up to 2 cm.

The security strip have the following colours:

1,000-krona banknote: purple

500-krona banknote: red

200-krona banknote: green

100-krona banknote: blue

Colour-shifting image

All denominations

The banknote has an image linked to the individual portrayed on the banknote. The banknote's denomination is also shown in the image. The image and the denomination gradually change colour between gold and green when you tilt the banknote. The image is placed to the right of the portrait on the face of the banknote.

The colour-shifting images have the following motifs:

1,000-krona banknote: Olive branch

500-krona banknote: G-clef

200-krona banknote: Clapperboard

100-krona banknote: Strip of film

50-krona banknote: Ship

20-krona banknote: Book

The watermark is visible from both sides when the banknote is held to the light. The watermark depicts the denomination of the banknote and its portrait. The denomination appears significantly lighter than the rest of the paper.

Intaglio printing

All denominations

Intaglio print makes the paper feel like a banknote and gives it a noticeable raised surface – run your thumb over it or scrape lightly with a fingernail. Among other places, intaglio printing has been used for the portrait and denomination on the obverse of the banknote.

The see-through picture is a pattern on the obverse of the banknote that, together with a pattern on the reverse, forms the denomination when you hold the banknote to the light.

Some series of banknotes have a brighter blue colour (see picture below). The Riksbank has been informed that certain cash registers and currency-counting machines therefore do not accept them. The banknotes are still valid and can be used to make payments. Nevertheless, the machinery manufacturers are updating their machines to accept the brighter banknotes.

Why are the security strips in different places on the banknotes?

The sideways position of the security strip on the 100, 200, 500 and 1,000-krona banknotes may vary somewhat from one banknote to another. This variation arises naturally in the banknote printing process, and is thus not a printing error. The size of the banknotes can also vary by +/- 1 mm and this is also a natural variation that arises in the printing process. If one measures from the left-hand side of the banknote to the left edge of the security band on the banknotes, the measurements differ as follows:

Denomination Number of mm from left edge of note to left edge of security strip on note
100 22,25 mm - 41,25 mm
200 23,75 mm - 42,25 mm
500 23,75 mm - 42,25 mm
1000 23,75 mm - 42,25 mm

Why is there occasional variation in colour?

Banknotes are produced in a printing process and deviations can therefore occur, even if they are unusual. There is just such a minor colour deviation on the reverse of some 1,000 krona banknotes, where the purple colour is slightly paler than normal. This affects neither the function of the banknote nor its security features – it is valid as a means of payment and can be used exactly as normal. To check whether the banknote is valid, you should tilt it. You will then see images that change colour and images that move and shift between motifs.

Counterfeit banknotes and coins

Payments may not be made using counterfeit banknotes and coins. To do so deliberately is a serious crime that is punishable by a prison sentence. It is also punishable to possess counterfeit banknotes or coins with the intention of distributing them.

If you detect a counterfeit banknote or coin, refuse to accept the banknote or coin. If you have already accepted a counterfeit banknote or coin, try to remember how you might have obtained it and report it to the police.
