Public Awareness on Ink-Staining Technology

Do Not Accept or Attempt to use Ink Stained Money!

Ink Stained Money is likely to be stolen money.

Banks in Malaysia including Hong Leong Bank has begun to implement the ink-staining technology (IST) at the Automatic Teller Machines (ATMs) and Cash Recycling Terminals (CRTs) to reinforce the security of these machines against thefts and robbery attempts.

Introduction to Ink-Staining Technology

The Ink-staining technology is a series of high-tech measures installed in ATMs and CRTs to effectively deter robbery attacks or any brute force attempts to steal money from these machines. Once an attack is detected, for example drilling, oxy-torching, explosion and carting – the IST will immediately be activated. All the banknotes in the machine will be stained with an indelible security ink.

The staining would make the banknotes identifiable as stolen and rendering such stained notes as totally valueless and not legal tender.

How to Identify Ink-stained Malaysian Banknotes?

•       The indelible security inks usually come in few colours -Red, Blue or Green.

•       Light smell of paint.

•       In general, the notes are stained with at least 20% front and back.

•      When handled without gloves, fingers may be stained when contact is made.
