Security Features of Singapore Paper Currency Notes

Paper notes are printed on cotton paper substrate with embedded security features such as the interwoven security thread, Portrait watermark and Ultra Violet fibres. This paper material is not available commercially for security control. During the printing process, an extensive range of security features are incorporated. All paper denominations ($50, $100, $1,000) have the same security features as set out below.

Portrait Watermark & Highlight Watermark
Genuine Description

A three dimensional multi-tone portrait watermark of the late Encik Yusof bin Ishak can be seen when the note is held up to the light. The watermark has a three dimensional appearance with areas in varying tones of dark and light.

 

The monotone highlight watermark is located below the Portrait watermark on the front of the note. It corresponds with the Braille pattern at the top right-hand corner of each denomination. The primary characteristic of the highlight watermark is that its extra thin area makes it appear clear and distinct when the note is held up to the light.

Security Thread
Genuine Description
The windowed machine-readable thread is interwoven in the paper running vertically down the face of the note. When held up to the light, the thread appears as a bold continuous line and it shows a series of text featuring the denomination numeral of the note and the word "SINGAPORE" in the four official languages.
Perfect Registration
Genuine Description

The Singapore Lion symbol appearing near the watermark is printed simultaneously with the same image on the front and back of the note. When the note is held up to the light, the Singapore Lion symbol on the front registers perfectly with the image on the back.
Intaglio Microtext
Genuine Description

The text "BOARD OF COMMISSIONERS OF CURRENCY SINGAPORE" or "MONETARY AUTHORITY OF SINGAPORE" is in micro-letters above the four official languages of the word "SINGAPORE" on the front of the note. To the naked eye, this appears as a single line but the details can be seen legibly with the aid of a magnifying glass.
Reverse Intaglio Microtext

Genuine Description

When magnified, the text "BCCS" or "MAS" in micro-letters in the shadow of the denomination numeral can be clearly seen.
Offset Microtext

Genuine Description

Front of the note - When magnified, the text "BOARD OF COMMISSIONERS OF CURRENCY SINGAPORE" or "MONETARY AUTHORITY OF SINGAPORE" forms a continuous pattern inside the denomination numeral.

Back of the note - When magnified, the text "MAJULAH SINGAPURA" forms a continuous pattern. As for the $1,000 note, the entire lyrics of Majulah Singapura are in microprint.
Ultra-Violet (UV) Visible Features

Genuine Description
This feature, in the form of the denomination numeral of the note, is present on the front of the note. It is invisible under ordinary lighting condition but glows brightly under UV light.
Fluorescent Ink

Genuine Description
The fluorescent pigment on the serial numbers and the seal on the front of the note glows brightly under UV light. This feature also appears on some parts of the designs on both the front and back of the note.
Asymmetrical Serial Numbers

Genuine Description
The asymmetrical serial numbering style has progressively larger digits in adjacent positions. One of the serial numbers appears horizontally, the other vertically. The serial numbers both glow under UV light.
Invisible Fluorescent Fibres

Genuine Description
When the note is viewed under UV light, more security features show up. Unlike most commercial papers, the paper of the note does not reflect UV light at all. Fibres which are invisible to the unaided eye are incorporated on both sides of the note surface. The fibres which cannot be seen in ordinary light will glow under UV light. This security feature can only be found on paper notes.

Tilt security features

Kinegram
Genuine Description
The kinegram appears as an octagonal foil on the front of the note. It contains an image of the denomination numeral which shifts as the note is tilted. On varying the viewing angle, one can also see the logo of BCCS or MAS transforming into the letters “BCCS” or the Singapore Lion symbol. The background of the kinegram is composed of shapes representing electron orbitals which change from bright to dark as the note is rotated. This background shimmers in an array of colours when rotated. These features are unique properties to the kinegram and cannot be replicated.
Security Thread
Genuine Description
The holographic images of the Singapore Lion symbol and the MAS logo can be seen on the silver-coloured thread when the viewing angle is varied.
Latent Image Patch
Genuine Description
Two distinctively different and latent images bearing the BCCS or MAS logo and the Singapore Lion symbol become visible alternately when the note is tilted at various angles. The latent image patch also glows brightly under ultra-violet light.

Intaglio Portrait
Genuine Description

The portrait of the late Encik Yusof bin Ishak dominates the front of the Portrait series notes. Hand-engraved and printed in intaglio ink, the portrait serves as a unique anti-counterfeiting feature. The fine lines of the engraving are difficult to imitate or reproduce.
Intaglio Prints

Genuine Description

The intaglio (raised) printing gives the note an embossed feel. Widespread use of this intaglio printing on the Singapore Arms, the engraved portrait, the word "SINGAPORE" and other areas offers good overall tactility. The prints are finely done so that tiny details are clearly defined. The intaglio printing of the denomination numeral of each note also helps recognition by the visually handicapped.
Each note has a Braille pattern printed in heavy intaglio ink at the top right corner of the front of the note, so that visually handicapped users can recognise the different denominations by touch.
