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
Warning Rejection Tags
The following warnings may occur during NFC verification. While these warnings don't necessarily indicate fraud, they should be carefully evaluated based on your security requirements:
| 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. |
DATA_INCONSISTENT | 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. |
