Document Verification Warnings and Errors
Our document verification process includes a series of automated checks to ensure the quality and validity of submitted documents. This page outlines the potential warnings and errors you might encounter during the verification process.
Fastfail Checks
Our system performs real-time checks on submitted documents to assure clarity and compatibility. When a document is uploaded, it undergoes a series of automated checks. These checks include:
- Ensuring all pages and sides of the document are uploaded
- Verifying that document number and name fields are present, clearly visible, and recognizable
- Checking that the document image is not a screenshot
- Confirming the image has not been cropped
- Verifying the document is not expired or issued in a forbidden territory (as per customer settings)
- Ensuring the document image has not been rejected in previous attempts
- Confirming the presence of a human face in the document photo
If a document fails these initial checks, the system immediately notifies the applicant and requests a document resubmission.
Warning Rejection Tags
Warnings allow applicants to proceed with verification after addressing the issue by retaking the document photo. Here are the OCR-related warning tags and their descriptions:
Tag | Description |
|---|---|
BARCODE_NOT_DETECTED | The system couldn't find or read the barcode on the document, which is necessary for document verification. This could be due to poor image quality or an unsupported document type. |
QR_NOT_DETECTED | The system couldn't find or read the QR code on the document, which is necessary for document verification. This could be due to poor image quality or an unsupported document type. |
MRZ_NOT_DETECTED | The system couldn't find or read the Machine Readable Zone (MRZ) on the document, which is essential for document verification. |
MINIMUM_AGE_NOT_MET | The user's age is below the minimum required for the application, which is necessary for document verification. |
DATA_INCONSISTENT | The Optical Character Recognition (OCR) data and the NFC chip data don't match, indicating potential document tampering or data inconsistency. |
COULD_NOT_RECOGNIZE_DOCUMENT | The system was unable to confirm the authenticity or validity of the provided document, which may be due to poor image quality or an unsupported document type. |
PORTRAIT_IMAGE_NOT_DETECTED | The system couldn't identify or process the portrait image of the document, possibly due to image quality issues or incorrect document positioning. |
DOCUMENT_NUMBER_NOT_DETECTED | The system was unable to locate or read the document number, which is crucial for document verification. |
DATE_OF_BIRTH_NOT_DETECTED | The system couldn't identify or process the date of birth on the document, possibly due to image quality issues or incorrect document positioning. |
NAME_NOT_DETECTED | The system couldn't identify or process the first name and/or last name on the document, possibly due to image quality issues or improper full name processing. |
MRZ_AND_DATA_EXTRACTED_FROM_OCR_NOT_SAME | There are differences between the information in the Machine Readable Zone (MRZ) and the data extracted through Optical Character Recognition (OCR), suggesting possible document alteration. |
MRZ_VALIDATION_FAILED | The Machine Readable Zone (MRZ) on the document doesn't meet the expected format or contains invalid data, indicating a potentially fraudulent or improperly issued document. This can also be caused by a low quality image that prevents proper reading of the MRZ. |
INVALID_DATE | One or more dates on the document (such as date of birth or expiry date) are not valid or don't match expected formats. |
DOCUMENT_EXPIRED | The document's expiration date has passed, rendering it no longer valid for use. |
DOCUMENT_NOT_SUPPORTED_FOR_APPLICATION | The type of document provided is not accepted or compatible with the current verification process. |
COULD_NOT_DETECT_DOCUMENT_TYPE | The system was unable to determine what kind of document was submitted, which may be due to image quality issues or an unsupported document type. |
DOCUMENT_NAME_DIFFERENT_FROM_OTHER_APPROVED_DOCUMENTS | The name on this document doesn't match the name found on other documents previously verified for this user, suggesting a potential identity mismatch. |
POSSIBLE_DUPLICATED_USER | The system identified a potential duplicate user with previously approved documents from another session, requiring further investigation. |
