Information is not stored on your phone and the Cellphone banking system uses encryption to ensure that the session is secure. Even if your phone is stolen, no-one will be able to transact on your phone. You also log on using your card number and a Customer Selected PIN (CSP) that you will have selected. As long as you keep these numbers to yourself, no one else will be able to access your bank accounts. WAP-based cellphone banking sessions are secured by the same 128-bit encryption used for internet banking. Make sure that you log out of cellphone banking when you have finished using it.
