  • iOS 4.0 and above
  • Android OS 2.1 and above
  • All devices must have a camera
  • The minimum requirement for image resolution is 1600 pixels x1200 pixels (therefore the device camera spec must be a minimum of 2mp). Images with lower resolution may pass the image quality verification, however, they may also be rejected more often.

Is Mobile Banking secure?
Rest assured. Mobile is safe to use!
  • Smartphones such as iPhone, Android and Blackberry have very controlled and secure operating systems
  • Mobile Banking uses 128 bit SSL encryption just like Online Banking, which basically encrypts and protects any transmission of data including customer account information
  • Our Mobile Banking solution uses strong Firewalls just like Online Banking, which protects from unauthorized or malicious intrusion
  • Mobile Banking uses your Access ID & Password for access, just like Online Banking. And just like with Online Banking, your account will lock down after three (3) incorrect attempts from your mobile device
  • Text messages are not secure, which is why SunBank will never send your name or account number through a text message.
