Counterfeit currency with fake holograms in Botswana

6 05 2008

After the fake Euros by Hologram Tam that have been a cause of worry in the European Union for long, the Bank of Botswana has issued an advisory to the general public that there are fake P100 and P50 bank notes in circulation, which are photo/scanned copies of genuine bank notes and thus, metallic features such as the hologram and windowed security thread appear as black/grey or brown patches on the surface of the counterfeits. It is noticed that counterfeiters have applied a thin film of a silver coloured substance on the hologram to give it a shiny effect like that on a genuine note.

The genuine bank notes are said to have a hologram that is silver coloured dual-image metallic patch with an image of the zebra and the number 100 on the P100 banknote hologram, which do not all appear at the same time, but switch from one to the other when the banknote is tilted and small diamonds appear in the background.

Furthermore, the images of the kingfisher and the number 50 on the P50 banknote hologram do not appear at the same time, but switch from one to the other when the banknote is tilted, with small kingfishers appearing in the background.

Holograms with new microscopic lettering

18 01 2008

Dai Nippon Printing Co. of Tokyo, Japan will market a new hologram label that combines 3-D computer graphic images with microscopic lettering.

Branded products use hologram labels to prove their authenticity, but in recent years the technology of forgery has advanced so far that it is difficult to distinguish real hologram labels from bogus hologram labels just by looking at the 3-D CG image.

To help people identify real labels, Dai Nippon Printing will incorporate the word GENUINE in microscopic lettering into the hologram. The letters are drawn with a line width of only 50 microns and are technically difficult to print, but readily viewable using a magnifying glass.

Dai Nippon Printing will charge 5 yen apiece for orders of 2 million labels and hopes to generate revenue of 3 billion yen (US$28 million) with this business during the next three years.
