seamen sail into biometric future the luxury cruise liner crystal harmony  currently in the gulf of mexico  is the unlikely setting for tests of biometric technology.  as holidaymakers enjoy balmy breezes  their ship s crew is testing prototype versions of the world s first internationally issued biometric id cards  the seafarer s equivalent of a passport. along with the owner s picture  name and personal details  the new seafarers  identity document incorporates a barcode representing unique features of its holder s fingerprints. the cards are due to be issued in february next year  in line with the revised un convention on seafarers  identity documents of june 2003. tests currently under way in the caribbean are designed to ensure that new cards and their machine readers  produced by different companies in different countries  are working to interoperable standards. results of the current tests  which involve seafarers from a wide range of occupations and nationalities  will be published by the international labour organisation (ilo) by the end of november. crystal cruises  which operates the crystal harmony  is exploring the use of biometrics but has not yet committed to the technology.  authenti-corp  the us technology consultancy  has been working with the ilo on its technical specifications for the cards.   if you re issued a seafarer s id in your country  you want to be sure that when the ship lands in a port in  say  my country you can validate yourself using whatever equipment we have installed   authenti-corp s ceo  cynthia musselman  told the bbc s go digital programme. she said french  jordanian and nigerian nationals would be the first seafarers to get the new id cards since their countries have already ratified the convention. it aims to combat international terrorism whilst guaranteeing the welfare the one million seafarers estimated to be at sea. the convention highlights the importance of access to shore facilities and shore leave as vital elements to a sailor s wellbeing and  therefore  it says  to safer shipping and cleaner oceans.  by increasing security on the seas as well as border control and protection  the cards will hopefully reduce the number of piracy problems around the world   said ms musselman.  it should be a safer environment for seafarers to work in  and will allow people protecting their borders to have confidence that the people getting off the ship are  in fact  seafarers.
