The one hundred euro note (€100) is one of the higher value euro banknotes and has been used since the introduction of the euro (in its cash form) in 2002. The note is used daily by some 332 million Europeans and in the 23 countries which have it as their sole currency (with 22 legally adopting it).
It is the third largest note measuring 147 millimetres (5.8 in) × 82 millimetres (3.2 in) and has a green colour scheme. The hundred euro notes depict bridges and arches/doorways in the Baroque and Rococo style (between the 17th and 18th century).
The hundred euro note contains several complex security features such as watermarks, invisible ink, holograms and microprinting that document its authenticity. In May 2012, there were approximately 1,652,287,100 hundred euro banknotes in circulation in 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 accountancy. 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 French franc and the Spanish peseta.
Slovenia joined the Eurozone in 2007, Cyprus and Malta in 2008, Slovakia in 2009, Estonia in 2011 Latvia in 2014, and Lithuania joined in 2015.
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, 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 hundred euro note measures at 147 millimetres (5.8 in) × 82 millimetres (3.2 in) and has a green colour scheme. All bank notes depict bridges and arches/doorways in a different historical European style; the hundred euro note shows the Baroque and Rococo style (between the 17th and 18th century). 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 twelve security features as listed below.

As of May 2013, there are approximately 1,721,763,600 €100 banknotes in circulation around the Eurozone. That is approximately €172,176,363,800 worth of €100 banknotes. 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 euro area.
Legally, both the European Central Bank and the central banks of the eurozone countries have the right to issue the 7 different euro banknotes. In practice, only the national central banks of the zone physically issue and withdraw euro banknotes. The European Central Bank does not have a cash office and is not involved in any cash operations.
There are several communities of people at European level, most of which is EuroBillTracker, that, as a hobby, it keeps track of the euro banknotes that pass through their hands, to keep track and know where they travel or have traveled. The aim is to record as many notes as possible in order to know details about its spread, like from where and to where they travel in general, follow it up, like where a ticket has been seen in particular, and generate statistics and rankings, for example, in which countries there are more tickets. EuroBillTracker has registered over 155 million notes as of May 2016, worth more than €2.897 billion.
