1, technical limitations: Face recognition technology is still in the stage of continuous development. For some special cases, such as poor lighting conditions, facial features changes, etc., the recognition accuracy has certain limitations.
2. Database matching problem: There may be errors or incomplete data in the database used by WeChat face unfreezing function, which leads to problems in matching the real identity of users.
3. Operation error: The user may have operation errors in the face thawing process, such as position deviation, facial expression inconsistency, etc., which makes the system unable to correctly identify.
4. Solution: Check whether the entered identity information is wrong, including ID number, name, etc. Confirm whether the identity information has changed, such as changing the bank where the account is opened, ID number and other information, and resetting the identity information; Delete the historical unfrozen face information and try to unfreeze the face again; Contact WeChat customer service for consultation, and provide complete identity information and other related materials, so that WeChat can officially verify the authenticity of identity.
