• Size: 35 × 45 mm (width × height)
• Background: White
• In colour
• Two recent photos.
• Paste them; do not staple or clip them to the form.
• Sign (or put your left thumb impression) across the photo on the left, so that part of it is on the photo and part on the form.
• Keep the photo on the right clean, with no mark; if the face cannot be seen clearly, the application may not be processed.
• A thumb impression must be attested by a Magistrate, a Notary Public or a Gazetted Officer, with official seal and stamp.
• How clear the photo on the card is depends on the photo you give.
• In the online scan-and-upload modes the signature is a separate file too: by Protean's instructions 200 DPI, JPEG, at most 10 KB, 2 cm × 4.5 cm.
• File for an online form: up to 20 KB, JPG/JPEG
