Safety Features / Authentication


In the Kip banknotes have been incorporated into a number of security features, so that the authenticity of
the banknotes can be reliably detected with a bit of attention.

For security features we talk about:

Stitch low pressure
Security thread
Examination register
Folios patrols or folios elements, both provided with a hologram
Pearlescent strips or optically variables colors
Fluorescent printing inks and fluorescent fibres in the paper
Infrared characteristic feature

These characteristic features must not have been applied with every bank note at the same moment,
it often depends also on the value (purchasing power) of the bank note, because the application also causes expenses.
Only once I wanted to have named all different security characteristic features.


Because the security characteristic features are similar with all bank notes of the last years,
I have taken only one bank notes as an example.


Explanation of the security characteristic features
at the example of 50000 Kip bank note.

Prefix and serial number (in this case in different colors)
Fluorescent fields (gray with silver pearl)
Fields with colored micro-letter series 1 = FIFTYTHOUSANDKIPS; row 2 = 50000KIPS always changing.
Watermark (General Secretary Khaisone Phomvihane)
Examination register
Security strip with text 50000 - in Lao and European, changing
In addition, colored fibers are scattered through the bank note that are not visible without a magnifying glass.
Only with UV light.




1. Planchets

Planchets are small colored-chips, mixed into the paper-pulp, added during production.
In the Laotian banknotes we find planchets of P-1 to P-5,
respectively in the (a) - Issue of bank notes, the Security Bank Note Company (USA).
In the following (b) - Issue * Reprints *, from the communist rebel organization "Pathet Lao" ordered,
and produced in Bulgaria, they had been dispensed on planchets.

P-1a (Issue of the Security Banknote Company)
P-1b (Issue of the Pathet Lao)




2. Stitch low pressure

By using the intaglio printing process occurs on the front of the banknote a tactile relief.
On the right frontside of the bank notes from P-35b to 10,000 Kip are also special
Distinguishing features been printed, the most important for the visually impaired to recognize the notes.
(For 1 a point and lines for 0)
In addition, the Kip banknotes are printed on special paper, that has a grippy texture.
Please note, that go through age and the wear some of these properties partially or completely lost.

P-35b (2003)
P-36b (2003)
P-37b (2003)
10.000 Kip
20.000 Kip
50.000 Kip
Note the arrangement of the points




3. Watermarks

If a bank note is considered in the back light, the watermark appears on both sides of the same unprinted area.
The predominant king's motive as well as partly, the worth number are to be recognized.
The watermark appears in the paper from variation of the paper thickness during the paper production.
Different areas are recognizable from which some are more brightly and other darker than the paper surrounding them.






4. Security thread

The older notes have a simple, thin security thread is embedded right into the paper.
The new banknotes are switching from a security thread, a security strip that is often labeled.

The 100,000 kip notes have a security strip.
A dark line runs the entire width of the banknote.
On the front of the note the strip is exposed and shimmers in all colors of the rainbow.
There you can recognize the number 100000, it is written in Lao.
On the back, the stripe is completely covered with paper.
A closer look at the stripe in the backlight, appears the number 100000 on Lao.
(alternately legible and mirrored).

Unfortunately, I could not face the scan, to show better, the function of the stripe recognize.




5. Examination register

The Examination-register is a feature, consisting of irregular character,
the one part printed on the front, and the other part is printed on the back.
They form up, to the light when looking through, a complete value number (e.g. in this case 50000) or a motive.



6. Folios patrols or folios elements, both provided with a hologram

If you tilt the banknote, are, depending on the viewing angle, the value of symbols or numbers in different colors
seen as a hologram.
I could not find a Lao bank note with this security feature.



7. Pearlescent strips or optically variables colors

With pearlescent strips e.g. the nominal values ​​provided on banknotes.
The performance figures appear in plan view, and then under a different viewing angle in different colors.
I could not find a Lao bank note with this security feature.



8. Microwritings

With the help of a magnifying glass tiny characters are to be recognized at some places on the bank note in different sizes.
The 0.8 mm overprint is readable in most cases with the naked eyes.
On the contrary 0.2 mm microwriting appears for the bare eye only as a thin line and is recognizable
only with the help of a magnifying glass.
Even the smallest print on the banknote should be razor sharp and not blurry.



9. Fluorescent printing inks and fluorescent fibres in the paper

Bank notes paper does not fluoresce, that is, it remains dark under UV lighting.
The fibres evenly embedded in the paper, under ultraviolet light shining on front and back either
in the colors Red, Green, Yellow or Blue.




10. Infrared characteristic feature

With the help of an infrared device parts of the stitch low pressure and the folios patrols become visible.
