The controversial card issued by Dorset NHS Primary Care Trust.
Schoolgirls in Dorset can now get the morning-after pill from their local chemist without needing to say a word.
Instead they simply hand over a special "contraception credit card" with their details filled in on the back.
The cards, which picture a young couple kissing, have been distributed by Dorset NHS Primary Care Trust to young people in the area.
Keith Williams, health programme adviser at the Dorset Primary Care Trust, said: "This scheme has been devised as a way of reducing the teenage pregnancy rate."
"If you are a teenage girl it is quite a daunting thing to go into a pharmacy and say out loud: 'I had unprotected sex.' There may be somebody in [the pharmacy] that you know and in the past that sort of thing may have put girls off from asking for emergency contraception."
But critics say that the cards will encourage harmful and careless sexual behaviour. Mike Judge of The Christian Institute told the Daily Mail: "In the same way that traditional credit cards can foster a reckless attitude to spending money, this will foster a reckless attitude to inappropriate sexual activity.
"To be telling teenage girls that they can hand over a card and get the morning-after pill in return is highly irresponsible."
Norman Wells of the Family Education Trust told The Daily Telegraph: "If they are handing out these cards to all and sundry, it doesn't seem to tie up with their claim that the pill is only given out after careful consideration."
A spokesman for the Society for the Protection of the Unborn Child said: "The morning-after pill delivers a high hormonal dose to women and girls which is 50 times that of the normal contraceptive pill."
"It is medically and ethically wrong to allow people to take this with minimal consultation."
