Security fibres

This is an image of a Receiver General Cheque

The RG cheque contains security fibres that are randomly interspersed throughout the paper. They are found on both the front and the back of the cheques:

  1. The fibres visible under normal lighting conditions are green. They fluoresce a bright green color under Ultraviolet (UV) light.
  2. The other fibres are not visible under normal lighting conditions. Under UV light, some of these fibres fluoresce a light blue color while others fluoresce a yellow color.
