An article in the Medical Journal of Australia by two prominent academics proposes requiring smokers to carry smart-card licences to enable health authorities to individually target quit messages, The Age reported.

A smart card would track the behaviour of smokers to allow targeted quit messages. The card, which builds on a proposal of anti-smoking advocate Prof Simon Chapman, also would make more difficult sales of tobacco products to underage persons, according to The Age. Prof Roger Magnusson of University of Sydney Law School and Prof David Currow, chief executive of the Cancer Institute NSW (New South Wales), were cited as the article authors.
