This type of security protection ensures that the cash stolen in a raid is marked or stained to prevent the criminal profiting from the proceeds of crime.

Purpose:

• The objective of these systems is to render stolen notes worthless to the extent that there is no gain to the criminal. This is a strong deterrent to committing further similar crimes.
• Recovered cash may produce forensic evidence to assist the police investigations.

Common Specification for all Indelible Staining and Note Marking Equipment:

When considering the type of equipment to use, you must ensure that it can achieve the following:

• Indelibly mark notes to achieve instant recognition that they have been stolen and render them worthless.
• Attract the attention of potential witnesses to a raid in progress.
  

Any system to be installed should comply with specification PAS 40, 2002, Class II issued by the British Standards Institute.


Smoke and Dye:

This system, when activated, dyes the banknotes and produces a large cloud of smoke.

Specification:

• A covert note spoiling device should be placed in each counter till.
• The device must look as authentic as possible to ensure that it is taken by or handed to the criminal instinctively.
• The system must be automatically activated to ensure the safety of the staff.
• The dye pack must be programmed to activate once the criminal has left the premises. A time delay of at least six seconds is recommended.
• It is recommended that the dye used is traceable to either a specific incident, the retailer or a manufacturer.
• All notes that are used in the construction of a dye pack must be recorded separately and kept in order to assist an investigation.
• The system used must produce sufficient smoke to attract attention to the criminal.
