Id verification is not automatically done in Zeevou. This step is there so that you can make sure all the gathered information (the signature or the ID) is correct. When everything is approved, you should go to the Guest Verification section in Booking view page and click on the red thumb and make it green. This means that you have verified the ID and it will be registered in the guest profile.
Please note that signing the Terms and Conditions doesn’t make this part green.
