Authentication Method

Authenticity verification is one of powerful aids of preventing counterfeit identification, mainly processed in three ways.

Authentication Method

MRT: Checks machine-readable zone if they are written in promised format.

Data Matching: Compares the data from machine-readable zone and human-readable zone and check if they match.

Database Check: Compares the ID info with issuing authority's database.

Authentication will run when all the required parameters are received. Missing one parameter won't trigger the process. When submitted via liveform, it will automatically differ depending on the project option but with API submission, please check the required parameters. For the required parameters by ID types, refer to the 'Authentication Input Data' page.

※Passports are authenticated with OCR AI scan result, without separate parameter.
