India's Bharat Coking Coal mining firm has announced that it will install an iris-based biometric attendance system in 12 mining areas in Jharkhand that will identify around 53,000 miners.The system, which will check attendance, is being installed following a successful deployment at the firm's head office in Koylanagar.”The biometric system in the head office has proved to be successful. Authorities will release payments of employees working at Koylanagar based on biometric data from July onwards. We have been asked to update our systems so that the system can be installed in our office, too,” said BCCL general manager of Baroda area, Prem Sagar Mishra, told the Times of India.In March, India's Andhra Pradesh state launched an iris-based identity management solution developed by US firm IriTech for use in pension distribution.In January, Indian biometrics expert Nandan Nilekani predicted that budget smartphones using iris scanners could become an important authentication tool for his country's biometric Aadhar unique ID number project.
