Data extraction

If you wish to request the document details from the user this section will provide you context on what this check entails. Yoti will extract data from thousands of ID documents from 200+ countries using Optical Character Recognition (OCR), with the option of a fallback to a manual data entry process in the event OCR is not successful.

This section will describe:

What a data extraction check is.
Outcome report with recovery suggestions.

The below checks are related to data extraction checks available at Yoti:

Name	Description	Resources	Manual check available
Text extraction	A request to obtain the data printed visually on a document, in structured form.	1x Document Resource	✅

If machine data extraction is not successful, at session creation there is an option to fallback to manual data extraction. This generates a ‘text data check’ automatically, and the document is reviewed by one of our document processing experts. The automated check is instantaneous.

Yoti will attempt to extract as much as data as possible depending on the document type.
