When visiting NSR POS offices, subscribers are required to carry vital documents along with them. The documents include the acknowledgement form printed from NSR with passport-sized photograph and duly signed by the subscriber. Also, subscribers are required to carry their proof of identity (POI) such as employee ID card, driving license, PAN card, voter ID card, passport or college ID card. The NSR POS is responsible for collecting the individual’s acknowledgement form, verifying the details along with proof of identity, collecting the biometric data (fingerprints) as well as the payment of registration fee which is Rs. 400 and applicable taxes. These documents are important without which the registration process cannot be completed.
