4. Why Mobile Users Need PDF SignCheck
Most citizens in Tamil Nadu download and view their TN e-Sevai / e-District certificates on Android and iOS mobile devices. However, mobile web browsers (like Chrome or Safari) and built-in PDF viewers completely ignore embedded digital signatures, showing no signature status at all. PDF SignCheck runs completely in your mobile browser, executing checks in-memory with zero file storage, providing Tamil Nadu mobile users with instant verified stamps.
5. Legal Validity of Digital Signatures under the IT Act, 2000
According to Section 5 of the Information Technology Act, 2000, electronic signatures validated against a licensed Certifying Authority (like those under the CCA India root) hold the same legal status as traditional handwritten signatures. They are legally binding and accepted by all government offices, courts, and banks. In Tamil Nadu, certificates issued through TN e-Sevai / e-District and signed by NIC-TN CA (National Informatics Centre Tamil Nadu) are fully valid once cryptographically verified. Tamil Nadu certificates are signed using certificates issued by NIC-TN CA under the CCA India framework. Our platform verifies the integrity of the document bytes.
