Common problems
I cannot see the button at the bottom.
Slowly swipe upward in the middle of the screen. If the keyboard covers the button, press Back once to dismiss the keyboard. Do not press Back repeatedly.
The camera does not open.
In Android settings, find PayON in the app list and check camera permissions. Menu names vary by phone. Contact support if it still fails.
Next is unavailable after taking photos.
Scroll down and check that every document says 촬영 완료. Foreign owners need separate front and back images. Wait if image processing is still in progress.
Are the code and password the same?
No. The verification code is a one-time six-digit number received in KakaoTalk. The password is at least six characters chosen afterward and used for future logins.
Approved, but employee management is missing.
Check that you used the owner’s registered number. Employees do not see this menu. If the owner cannot see it, provide support with the app version and the last four digits of the phone number.
An error or blank screen appears.
If a payment is in progress, check its result before retrying. During application or login, note the error and step for support. Do not uninstall or clear app data before receiving guidance.
Tell us the step number, the message shown, and the last four digits of your phone number. Never send a password, verification code or ID photo by ordinary message.
