Can I match the user's face with the portrait image on the Aadhaar in the Aadhaar API?

Yes. We provide Face Match with Aadhaar, which can be used to match the user’s face with the portrait image of the user on the Aadhaar.

During Aadhaar number verification, can I verify the Aadhaar-linked mobile numbers of customers while?

Yes. Offline Aadhaar in XML mode is used to verify the registered or linked mobile number. You can enter the mobile number to be verified, and we will provide you with the status as output.

What if the uploaded XML or e-PDF file is tampered with during the Aadhaar number verification?

The signature attached to the file is verified by us. If the signature does not match with the original, the file is rejected, and you are protected from any malpractices.

Will any pin be generated for the customer?

No. Signzy’s Offline Aadhaar Verification API will give an unlocked XML that does not require a pin. A pin is generated only if the XML is locked.

How can I extract Bank or PAN details from Aadhaar using the Aadhaar API?

You can’t. Both of these data are retrieved from different sources. Aadhaar does not provide any access to that data.

Can we use OTP or biometrics for Aadhaar Authentication or eKYC?

No. Private institutions are not allowed to extract from the UIDAI database under the guidelines of the Supreme Court. Only Banking and Telecom entities are allowed to do so.
