Security Features:

1.   Latent Image (hidden). 

The effect of this image is created through the process of Intaglio printing.  The shadows caused by microscopic channeling and slots create an image that is only perceivable when observed under a light, at a 45-degree angle.

2.   Mark for the Visually Impaired.

It consists in the placement of a geometric figure in bas relief along the lower left-hand border of the banknotes.

3.   Micro-printing. 

Small-letter inscriptions which, upon simple inspection, resemble a solid line but can only be deciphered if seen through a magnifying lens.

4.   Asymmetrical horizontal numbering.

Numbering characterized by ascending type fonts; each letter and number is of a different and increasing size.

5.   Year of printing.

The year in which the banknote was printed is located on the front of the banknotes and helps identify the series to which it belongs.

6.   Vertical numbering.

Numbering appears in the form of printing same-size letters in a vertical line along the right-hand edge of the banknotes.

7.   Security thread.

A thin thread made of synthetic material, with no text, is inserted within the paper’s mass.
