A quality approach to biometric imaging

The author considers his discovery of vein patterns some years ago now and how he developed a very simple reader to obtain an Infra Red recording of the subcutaneous absorption pattern of an individual. The reader employed a number of IR LEDs and IR sensitive photo diodes in an array which when drawn across the surface of a subjects skin would provide a characteristic absorption pattern for the individual. Essentially a bar code reader for people. He assigned the rights in the intervention to the British Technology Group (BTG) and anticipated the security industry and the Banks beating a path to the BTGs doors for access to this technology. Alas like many inventors in Britain he was disappointed by the timidity of British Industry many wanted to market the system none wanted to develop it. He resolved in 1990 to develop this technology so that it couldn´t be ignored
