NFC Authentication Warnings and Errors
Our NFC-based authentication process includes automated checks to verify the authenticity of electronic documents through their embedded NFC chips. This page outlines the potential warnings and errors you might encounter during the NFC verification process.
NFC Verification Process
When performing NFC-based authentication, the system attempts to:
- Establish connection with the document's NFC chip
- Read and validate the chip's digital signature
- Compare the data stored in the chip with the OCR-extracted data
- Verify the authenticity of the chip using appropriate certificates
Automatic Decline Conditions
The following conditions will always result in an automatic decline regardless of application settings:
NFC_AND_OCR_DATA_NOT_SAME- The Optical Character Recognition (OCR) data and the NFC chip data don't match
Configurable Verification Settings
Applications can configure how the system handles various NFC verification issues by setting actions for different risk categories:
-
Skipped NFC Validation
- Risks:
SKIPPED_NFC_VALIDATION - Configurable action: Decline, Review, or Approve
- Risks:
-
Unverified NFC Chip
- Risks:
NFC_CHIP_NOT_VERIFIED - Configurable action: Decline, Review, or Approve
- Risks:
-
Data Inconsistency
- Risks:
NFC_AND_OCR_DATA_NOT_SAME - Configurable action: Decline, Review, or Approve
- Risks:
NFC Verification Warnings
Tag | Description |
|---|---|
SKIPPED_NFC_VALIDATION | The Near Field Communication (NFC) chip validation process was not completed, potentially due to technical issues or lack of NFC support. This could happen if the user's device doesn't support NFC reading or if there were connectivity issues during the verification process. |
NFC_CHIP_NOT_VERIFIED | The Near Field Communication (NFC) chip was not verified, potentially due to missing certificate to verify the signature of the chip, or the chip is designed to not be verified. This might occur with older document types or when the necessary verification certificates are not available. |
NFC_AND_OCR_DATA_NOT_SAME | The Optical Character Recognition (OCR) data and the NFC chip data don't match, indicating potential document tampering or data inconsistency. This is a serious warning that could indicate document manipulation or forgery. |
Warning Types
Each risk is assigned a warning type based on your application's configuration settings. Warnings fall into three severity categories:
| Type | Description |
|---|---|
ERROR | Critical issues that resulted in setting the session to `Declined` |
WARNING | Issues that require attention that resulted in setting the session to `In Review` |
INFORMATION | Informational messages that don't affect verification outcome |
