New doctors in India's southern Karnataka state are being given biometric ID cards to prevent impostors from defrauding patients.Over 100,000 doctors have already have applied for the smart cards, which will be issued to anyone who has just completed MBBS degree and has sought registration, reported the Deccan Herald.For existing practitioners, the card is being issued at the time of licence renewal.Once practitioners apply for licence renewal, their documents will be verified, photographs scanned and uploaded.Fingerprints will also be taken. This data will later be incorporated into a smart card which bears the registration number.”There are many practitioners who would have left the country. Some would have died. Once they apply for renewal, such cases can be identified,” said Dr T A Veerabhadraiah, a KMC member.The card data can also store if a doctor has been sued or if a complaint is lodged against him with the Council.
