Facial recognition is failing to work properly on Apple's first foldable smartphone, the iPhone Duo, when users try to obtain KB Kookmin Bank's mobile certificate, according to industry sources.
Some customers attempting to issue a KB Kookmin certificate through the KB Star Banking app on the iPhone Duo cannot complete the authentication process because of facial recognition errors, financial industry sources said on the 27th.
Complaints have piled up on online communities since the iPhone Duo launched on the 23rd.
Kookmin Bank is investigating the cause.
"We have secured a device and are running tests, but the exact cause has not yet been identified," a Kookmin Bank official said.
