This document describes a proposed online SIM card registration system. The current SIM registration process involves filling out paper forms, providing documentation, and couriering information for data entry. This system has issues like errors, fraudulent activities, and high costs. The proposed system allows for online form filling on a mobile app, capturing photos and biometric data, uploading information directly to a central server, and printing receipts. This paperless system eliminates errors and costs while improving security through encryption and authentication. If implemented, it could help reduce phone crimes in India by linking SIMs to verified identities.
