Yes, The PAN OCR and verification SDK or the Verification API only checks and returns the Name, PAN number, and Date of birth of the customer. Since the API provided by the government doesn't check or return the photo of the user, it is possible to replace the photo in a given PAN card with that of another person.
As such, we recommend using a combination of Aadhaar or any other OVD along with PAN to make sure that the customer is, who he says he is.
In case of PAN the Fetch API call gives the following response,
"response_status": { "code": "000", "message": "Data fetched successfully", "status": "SUCCESS" }
To view the exact details of the transaction, you need to decode the base64 in the "kyc_info", and then you will see the pan card details with whether it has been verified successfully for the PAN database or not.
After decoding the base64, you can check key "document_verification_status", if it was a success or failure.
