Tips for a Perfect Result

- Keep your face straight, eyes open, mouth closed — no cap or dark glasses.
- Sign with a black ink pen on plain white paper, then photograph it in good light.
- Make the signature big — it should fill most of the box. Tiny signatures are a common reason for rejection.
- RRB asks for the signature in running handwriting — not in capital letters.
