The security thread can be seen as a dark line in the middle third of the banknote. In the security thread 20 EURO in small letters and 20 in microletters, alternating in normal writing and mirror writing.

The paper is dull, the European flag glows in yellow or green, the stars of the flag are orange. In the middle of the banknote, parts of the circle of stars and small circles glow red. Fibers embedded in the paper glow in green, red and blue. The watermark is not visible.

At several places of the banknote motif, there is microlettering, which looks pin sharp even under a magnifying glass.

The copyright line has a feelable raised printing. All Euro banknotes, irrespective of date of production, bear the year 2002.

When you hold the banknote against the light, the value numeral 20 in the watermark is brighter than the surrounding paper. There is no dark outline around the numeral. When you lay down the banknote on a dark surface, the value numeral 20 appears to be darker than the surrounding paper. This effect can be seen from the reverse side laterally reversed.

When you hold the banknote against the light, the incomplete lines of the front and reverse side add to the value numeral 20. This effect can be seen from the reverse side laterally reversed.

Depending on the viewing angle, the Euro symbol "€" and the value numeral 20 interchange. When you tilt the banknote, prismatic colours move upward and downward through the hologram stripe
