If your Internet Banking session is idle for more than 10 minutes it will time out. You will be asked to Log On again before your next request can be carried out.
This feature is designed to provide some protection in the event that you leave your computer unattended.
Ideally, you should never leave your computer unattended when you are logged on. Always make sure that you Log Off when you’ve finished your session. This will prevent any unauthorised person gaining access to your information.
