Supporting documents

AI Tools

Yoti offers the ability to request additional documents to enhance the verification of the user. You can request this on its own as part of a new session or include in your current session.

Please see our document comparison feature to compliment supporting documents.

Good to know

Yoti will only compare the NAME of the users between the documents uploaded.

Currently Yoti supports the ability to upload a:

Text Extraction

A request to obtain the data printed visually on a document, in structured form. If machine data extraction is not successful, there is an option (selected at session creation) to fall back to manual data extraction. This generates a ‘text data check’ automatically.

const supportingDocumentDataExtraction = new RequestedSupplementaryDocTextExtractionTaskBuilder()    .withManualCheckFallback()    .build();​const sessionSpec = new SessionSpecificationBuilder()    // ...    .withRequestedTask(supportingDocumentDataExtraction)    // ...    .build();

Manual Data extraction	Description
withManualCheckFallback	This will initiate manual data extraction only if the automatic extraction fails. We strongly recommend this option.
withManualCheckNever	If the ID fails on automatic extraction, Yoti will not attempt manual extraction and will return a failure in the report.
withManualCheckAlways	The document is always referred for manual review at Yoti's Security Centre, regardless of whether machine data extraction has succeeded or failed.

Filtering documents

You can filter documents by country or by document type.

Node.js
Java
PHP

const supportingDocument = new RequiredSupplementaryDocumentBuilder()    .withObjective(supportingDocumentObjective)    .withCountryCodes(["GBR","USA"])    .withDocumentTypes(["UTILITY_BILL"])    .build();

Document comparison check

For requesting one ID document and one supporting document from the user please see below for configuration:

Node.js
Java
PHP
C#
Go
JSON
    
 
const documentComparisonCheck = new RequestedIdDocumentComparisonCheckBuilder().build();​const sessionSpec = new SessionSpecificationBuilder()    // ...    .withRequestedCheck(documentComparisonCheck)    // ...    .build();
Copy

Yoti will check and compare the following user data and provide you with a sub check result:

Name
