Why format your Left Thumb Impression (LTI)?
The Air Force Common Admission Test (AFCAT) uses biometric verification during the Ground Duty (Technical) examination process. If your uploaded Left Thumb Impression (LTI) is smudged, too dark, or exceeds the strict 50KB limit, the portal will reject your application. You must press your thumb firmly on a generic ink pad (black or blue ink) and stamp it on plain white paper. Our processor ensures the final scan is perfectly compressed to meet the 2026 official guidelines.
Official LTI Rules
