Dilihat · Diraba · Diterawang— the three ways Indonesians check a note's security features
Anatomi Rupiah
This site shows how the security features of Rupiah banknotes work — and how to check them yourself.
Almost every Indonesian can recite those three words. Far fewer could say what a watermark actually is, why the printing feels raised, or what the security thread is doing inside the paper. Here it is taken apart, layer by layer.

In short
What this site does
Explains each security feature on Rupiah banknotes: what happens inside the material, and what you should look at, feel for, or hold to the light.
What it does not do
It does not scan notes, use a camera, or ever tell you whether a note is genuine or counterfeit.
Who decides
Bank Indonesia. If a note troubles you, take it to a bank or a Bank Indonesia office.
Four checking channels
Colour here is not decoration. Each hue means one way of checking, used consistently on every page.
Dilihat — seen
Features visible in ordinary light.
Diraba — felt
Features felt with a fingertip. Not possible through a screen.
Diterawang — held to light
Features that appear when the note is held up to the light.
Machine & UV
Features for machines and ultraviolet light — the fourth channel, beyond the three.
One of the three cannot be done on a screen
Diraba is a check made with a fingertip. A screen has no texture, and a vibration does not imitate raised printing. We will not pretend otherwise.
