TicketThe term ticket it has several uses according to the context. The most common meaning is linked to paper money: that is, to the document printed by the authorities that is used as legal medium of pay.

For instance: “To buy this car you will need a lot of tickets”, “Yesterday they gave me a fake ten peso bill”, “I don’t have a single ticket: I don’t know how I’ll buy food”.

This concept, in this sense, is the ticket of Bank. This is fiat money (based on trust) issued by the monetary authority of a country. These banknotes were created to replace or complement metallic coins, which are difficult to move and store in large quantities.

The first banknotes were created in the 7th century in China. Just in the XVII century were adopted on the European continent, and in the following century they spread throughout the world.

In the same way that it happened and continues to happen with the coins of metal, which were made in gold or silver at the time, the banknotes also suffered inevitable counterfeiting by those who do not wish to obtain their own money by legal and fair means. With paper, counterfeiting proliferated and became easier, partly because it cost much less than metal coins.

In order to avoid fakes or at least control it to minimize its spread, banks have been applying various measures of security, which have evolved over time to deal with the ingenious tactics of counterfeiters.

* optically variable ink: East material it changes color according to the angle at which the light hits.

Apart from cotton, it is common for paper money to be made from textile fibers such as linen.
