How to Validate e-Aadhaar Card Letter Signature - Validity Unknown to Signature Valid

Once downloading Aadhaar Card from the UIDAI Website, when you access the PDF file you will notice a Validity Unknown with a yellow colored question mark. And if you print the Aadhaar with such sign then on the printout too you will get to see the same error of Validity Unknown.

 

 

 

This Icon or Sign is nothing but an Digital Signature which confirms signer’s identity. To make this digital signature verified, you need to perform few additional steps after the download. And once performing those steps you will get to see Signature Valid with green tick mark on your Aadhaar, instead of the yellow question mark Signature not verified error.
