The letter is a communication addressed to various offices and departments of the Employees' State Insurance Corporation (ESIC) regarding the Aadhar seeding process for insured persons and their family members. It highlights the unsatisfactory progress of Aadhar seeding and the inability of field offices to meet daily targets. The main issue raised is the problems faced with OTP-based authentication, such as non-receipt of OTP and changes in mobile numbers. To address this, it is suggested that biometric authentication be introduced alongside OTP-based authentication. The ICT Division has developed an application for biometric authentication, and two approved models of biometric devices are recommended. The devices should be procured following the due process. Each office has specific quantities to procure based on their requirements. All field offices are directed to use these biometric devices to achieve daily targets. The letter also provides details of the approved biometric devices and the process for procurement.
