The Security PIN Code is an added layer of protection for this service. Once you have your Funds Transfer account fully activated and ready to go, you will be asked to designate a 4 character security PIN code the first time you want to schedule a transfer. This code must be 4 digits long, and can consist of numbers and/or letters and is case sensitive. Enter the code you've selected, and then verify it by re-entering. Please keep this Security PIN in a secure place. We will require it every time you want to request a Funds Transfer to/from an external account using this service.
