Steps
Capture the NFC chip session data client-side via the Document Reader mobile SDK during document scanning
Submit the captured chip session payload to Regula's server-side verification service instead of trusting the on-device result alone
Have the server independently re-run Passive Authentication (PA) against the chip's signed data groups and issuing country's certificate
Where supported by the document, also validate Active Authentication (AA) or Chip Authentication (CA) results to detect chip cloning
Combine the server-verified chip result with the visual/MRZ document check before accepting the document as authentic
Known gotchas
Passive Authentication alone confirms data-group integrity but not that the chip itself is genuine — pair it with Active/Chip Authentication where the document supports it, or a cloned chip can still pass PA
Passive Authentication validity depends on trust in the issuing country's Document Signer Certificate chain (CSCA), which requires maintaining an up-to-date master list
Server-side re-verification exists specifically because on-device-only results can be tampered with in transit — skipping it removes that integrity guarantee
