No — a photo of your ID on your phone or a digital locker screenshot is not accepted as ID proof.
You must carry the original physical photo ID (Aadhaar card, voter ID, PAN card, driving licence or passport).
Carry the same ID you mentioned in the application form if the notification asks for it.
Mobile phones are banned inside the exam hall anyway, so keep yours outside the centre.
Pair the original ID with your printed admit card — both are checked at the gate.
