LTI vs RTI: Which one should you upload?
Always read the specific exam notification. However, if the notification is silent or you are confused, here are the standard rules followed by major Indian recruitment bodies:
👨 Male Candidates
This is the universal standard for male applicants across SSC, UPSC, IBPS, and Railway exams.
👩 Female Candidates
Standard rule for females in state exams and older recruitment boards. Note: SSC now often asks for LTI for *all* candidates, so check your specific notice!
What if my thumb is injured? Use the impression of the other thumb. If both are injured, use the next finger on the left hand (index finger), and notify the invigilator during the exam.

Is it safe to upload my biometric thumbprint here?
Yes, 100%. Our tool runs completely client-side in your web browser. Your thumb impression is processed locally using the canvas API and is never uploaded or saved to our servers. You can even disconnect your internet while using the tool.
Why does my exam portal reject my thumb impression?
Portals reject thumbprints if the file size exceeds the limit (e.g., 20KB for SSC), if the format is not JPEG (e.g., iPhone HEIC or scanned PDF), or if the print is smudged and unreadable. Our tool ensures correct size, format, and clarity.
