The writer of the letter Holograms for drugs rule: Who's liable for deaths? on holograms on pharmaceutical products, has very little idea of the tight procedures and security controls that are used in the issuance of authentication holograms, otherwise he wouldn't hypothesise about the possibility of buying a fake drug with a genuine hologram on.
Of course, the 'ordinary folks' he refers to may not know all the features of the hologram - because that's the idea. Do these ordinary folks know all the security features embedded into the banknotes they use every day?
Of course not, because if they did they wouldn't be called security features. Do these ordinary folk examine banknotes for even those security features that they might - just might - know about? Probably not.
And this is why the security features in the images on the holograms will be known only to inspectors, the people trained and responsible for checking the authenticity of the hologram and therefore, the pharma product it is on.
The writer is the publisher Holography News and is the general-secretary of the International Hologram Manufacturers Association.
