TLDR: The Enhanced NFC ID check report includes flags from document and facial similarity checks. Document flags cover chip validation, data comparison (e.g., name mismatches or special characters), and cloning detection. Facial checks verify face matching and scan authenticity. Flags often result from data entry errors, poor scan conditions, or technical issues, with guidance provided for resolution.
Enhanced NFC ID check report
Included in your Enhanced NFC ID check report is a breakdown of any flags on the document report and the facial similarity report.
Document Report flags
The table below breaks down the checks that are run as part of the Enhanced NFC ID document check.
| Type of check | What this means |
| Chip and Document validation |
Data is extracted from the biometric chip. The signing key and digital signature held on the chip are verified to ensure this document is government-issued and belongs to your client. A flag under this section likely means that the governing body who issued the document have not provided our supplier with the country certificate required to verify it. Please raise a query with the Client Support team for further information. |
| Data Comparison |
Personal data extracted from the biometric chip is directly compared to the data provided by the client in the app. If there are any mismatches, this section of the report will flag and more information will be provided in Appendix 2 of the report. A common reason for this flag is the client entering their name differently to how it appears on their ID. The name entered into the app must match the name on the document exactly in order to fully pass this section. A flag may also be raised if the client's name includes special characters, or is more than 39 characters in length. |
| Cloning Detection (Active Authentication) |
Active authentication verifies the public and private encryption keys associated with the biometric passport chip. Each issuing body (governments) provides these encryption keys to our supplier, who in turn is able to decrypt the key and verify the authenticity of the chip. The most common reason for a flag on this section is down to the connection being interrupted or the signal being weak during the verification of the encryption key on the chip. This is often down to covers or cases on the passport or mobile device. To resolve this, the client should try this task again on a new activity and ensure all covers and cases are removed prior to completing the chip read. If the result does not change when a second Enhanced NFC ID check has been properly carried out, please let the Client Support team know straight away. |
Special characters in name
You may see a Data Comparison flag if the client's name includes non-latin characters. If this is the case, the client will need to enter their name as it appears on their ID, but replace the special character(s) with its latin counterpart. For example, if your client’s surname is Müller, they will need to enter this in the app as Muller.
Name longer than 39 characters
The name field on the passport chip can store up to 39 characters. If a client's name is longer than this, you may see a Data Comparison flag on their report, as the name displayed on the paper copy of the document may not match the contents of the chip.
You can check to see exactly what name has been extracted in Appendix 2 of the ID report.
Facial Similarity Report
The table below breaks down the checks that are run as part of the Enhanced NFC ID 'liveness' check.
| Type of check | What this means |
| Face Comparison |
Checks to ensure that the face included in the facial scan matches the photo stored on the biometric chip. A flag here could mean that the client looks very different to their passport photo, or that the facial scan was completed by a different person than the owner of the passport. |
| Visual authenticity / Image Integrity |
Confirms the 'liveness' of the facial scan - that it was done live and in person, and was not scanning a photo or a face on a screen. A flag under this section usually means that the client's face was not visible to the camera when the scan was attempted, maybe due to bad lighting or a face not detected on the screen. |
What other types of flags might appear?
In addition to the flags related to documents and facial scanning listed above, Original ID reports may also include flags relating to screening, address verification, international address verification or CCJs & Insolvency.
