Experts of Australia want to introduce a 'smartcard licence' scheme for people to purchase cigarettes.
Retailers would have to check the licence before every sale to verify that every pack sold is purchased by an adult.
Health and legal academics have claimed that the scheme will help health authorities to track the behaviour of smokers and better target quit messages to them, News.com.au reported.
According to an article published in the Medical Journal of Australia, University of Sydney Law School's Professor Roger Magnusson and chief executive of the Cancer Institute NSW Professor David Currow said a licence scheme could also make it harder for children and adolescents to buy cigarettes.
