LONDON - JULY 27:  A woman looks at a casino website on July 27, 2004 in London. Internet gambling websites should introduce age-verification checks to prevent children from betting online, NCH (a children's charity) urged on Tuesday. The call by NCH came after it found that a 16-year-old girl was able to register with 30 gambling sites after lying about her age.  (Photo iillustration by Graeme Robertson/Getty Images).
