Other Security Features

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 ultra-violet (UV) light.

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.

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.

These line structures appear at the right of the front design and on the areas above and below the portrait watermark on the back of the note. The hidden distortions will appear in these areas when the note is colour-copied.

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.
