The twenty euro note (€20) is the third-lowest value euro banknote and has been used since the introduction of the euro (in its cash form) in 2002. The note is used in the 22 countries which have it as their sole currency (with 20 legally adopting it); with a population of about 332 million.
It is the third-smallest note, measuring 133x72mm with a blue colour scheme. The twenty euro banknotes depict bridges and arches/doorways in Gothic architecture (between the 13th and 14th century CE).
The twenty euro note contains several complex security features such as watermarks, invisible ink, holograms and microprinting that document its authenticity. In October 2011, there were approximately 2,755,346,800 twenty euro banknotes in circulation around the Eurozone.
The euro was founded on 1 January 1999, when it became the currency of over 300 million people in Europe. For the first three years of its existence it was an invisible currency, only used in accountance. Euro cash was not introduced until 1 January 2002, when it replaced the national banknotes and coins of the countries in eurozone 12, such as the Irish Pound and the Austrian schilling.
The changeover period 
The changeover period during which the former currencies' notes and coins were exchanged for those of the euro lasted about two months, going from 1 January 2002 until 28 February 2002. The official date on which the national currencies ceased to be legal tender varied from member state to member state. The earliest date was in Germany, where the mark officially ceased to be legal tender on 31 December 2001, though the exchange period lasted for two months more. Even after the old currencies ceased to be legal tender, they continued to be accepted by national central banks for periods ranging from ten years to forever.
Notes printed before November 2003 bear the signature of the first president of the European Central Bank, Wim Duisenberg, who was replaced on 1 November 2003 by Jean-Claude Trichet, whose signature appears on issues from November 2003 to March 2012. Notes issued after March 2012 bear the signature of the third president of the European Central Bank, incumbent Mario Draghi.
Until now there has been only one series of euro notes, however a new series, similar to the current one, is planned to be released. The European Central Bank will, in due time, announce when banknotes from the first series lose legal tender status.
As of June 2012, current issues do not reflect the expansion of the European Union to 27 member states as Cyprus is not depicted on current notes as the map does not extend far enough east and Malta is also missing as it does not meet the current series' minimum size for depiction. Since the European Central Bank plans to redesign the notes every seven or eight years after each issue, a second series of banknotes is already in preparation. New production and anti-counterfeiting techniques will be employed on the new notes, but the design will be of the same theme and colours identical of the current series; bridges and arches. However, they would still be recognisable as a new series.
The twenty euro note is the third smallest euro note at 133 millimetres (5.2 in) × 72 millimetres (2.8 in) with a blue colour scheme. All bank notes depict bridges and arches/doorways in a different historical European style; the twenty euro note shows the gothic era (between the 13th and 14th century CE). Although Robert Kalina's original designs were intended to show real monuments, for political reasons the bridge and art are merely hypothetical examples of the architectural era.
Like all euro notes, it contains the denomination, the EU flag, the signature of the president of the ECB and the initials of said bank in different EU languages, a depiction of EU territories overseas, the stars from the EU flag and thirteen security features as listed below.
Security features 
As a lower value note, the security features of the twenty euro note are not as high as the other denominations, however, it is protected by:
- A hologram, tilt the note and one should see the hologram image change between the value and a window or doorway, but in the background, one should see rainbow-coloured concentric circles of micro-letters moving from the centre to the edges of the patch.
- A EURion constellation, special printing processes give the euro notes their unique feel.
- A glossy stripe, tilt the note and a the glossy stripe showing the value numeral and the euro symbol will appear.
- Watermarks, it appears when the banknote is against the light.
- Raised printing, special methods of printing makes the ink feel raised or thicker in the main image, the lettering and the value numerals on the front of the banknotes. In order to feel the raised print, run your finger over it or scratch it gently with your fingernail.
- Ultraviolet ink, Under ultraviolet light, the paper itself should not glow, fibres embedded in the paper should appear, and should be coloured red, blue and green, the European Union flag looks green and has orange stars, the ECB President signature turns green, the large stars and small circles on the front glow and the European map, a bridge and the value numeral on the back appear in yellow.
- Microprinting, On numerous areas of the banknotes you can see microprinting, for example, inside the "EYPΩ" (EURO in Greek characters) on the front. You will need a magnifying glass to see it. The tiny text is sharp, and not blurred.
- A security thread, The security thread is embedded in the banknote paper. Hold the banknote against the light - the thread will appear as a dark stripe. The word "EURO" and the value can be seen in tiny letters on the stripe.
- Perforations, Hold the banknote against the light. You should see perforations in the hologram which will form the € symbol. You should also see small numbers showing the value.
- A matted surface, the note paper is made out of pure cotton, which feels crisp and firm, but not limp or waxy.
- A serial number.
As of October 2011, there are approximately 2,755,346,800 €20 banknotes in circulation around the Eurozone. That is approximately €55,106,936,900 worth of €20 banknotes (as of October 2011). The European Central Bank is closely monitoring the circulation and stock of the euro coins and banknotes. It is a task of the Eurosystem to ensure an efficient and smooth supply of euro notes and to maintain their integrity throughout the eurozone.
