Australia is introducing punishments of up to three months in prison or a fine of up to AU$1,250 (US$950) for anyone who refuses an on-the-spot fingerprint scan.Attorney-General John Rau is bringing in the legislation to expand biometrics' use following an an election promise to give the police new powers.Rau said police currently have limited powers to use the fingerprint scanners, as they need to have already arrested a person.Under the new legislation set to be released for consultation, before a person can be scanned police have to have “reasonable cause'' to suspect that person has committed, is committing or is about to commit an offence or may be able to assist in the investigation of an offence.Sine last February, some 150 portable fingerprint scanners have been deployed across South Australia and a trial conducted last year resulted in several people being arrested after being scanned.However, Law Society president Rocky Perotta told The Herald Sun that he had “strong concerns about the idea of compelling someone to submit to a fingerprint scan on the spot”.”Being forced to have a fingerprint scan is a serious intrusion on privacy and should only be justified in extreme cases, which is why the current position only allows authorities to compel a scan after a person has been arrested,'' he said.
