Hello,

If your fingerprints don’t get verified on the NEET exam day, you may still be allowed to appear for the exam, but the invigilators will follow specific guidelines set by NTA.  They may verify your identity through alternative means like photo ID and admit card. Any discrepancy is usually reported to the authorities for further action. It's important to remain calm and cooperate with the exam staff to resolve the issue.

Hope this helps you,

Thank you
