High-end Card Security is Linked to Specific Covert Tactics

Security on an ID or access control card is imperative for the safety of your organisation.

There are two types of security features – overt features are visible with the naked eye and covert features that require an additional assistant for viewing.

A secure card has a balance of both covert and overt features.

These 3 tips are covert security features and things that those validating entry or identification can recognise as valid or fraudulent using specific tools.

Ultra-violet Ink – Reprint logos, text or card holder’s identification in UV ink. Under a UV light source, the light reflection will be visible. Under normal light, the ink is not visible.

Invisible Personal Information (IPI) - IPI encodes personal data into the photo. This information is invisible to the naked eye, but can be seen through a simple decoding device as seen on the left.





Optically variable ink (OVI) Printing – Colour shifting inks reflect various wavelengths in white light differently, depending on the angle of incidence to the surface. An unaided eye will observe this effect as a change of colour as the viewing angle is changed.

A colour copier or scanner will only scan the document at one fixed angle relative to the card’s surface making unauthorised replication very difficult.

On the right you can see an example of OVI printing
