If you wish to try or show someone the Demo mode of the App, you must login by pressing the delete button for 2 seconds. That way you will be granted access to the demo mode: you will have to enter any four digits as a pin code and the App will be opened for you to explore.
After that you can explore what kind of functionalities the App supports. You can try making a deposit (any kind of secure pattern will be accepted on the Demo version), create your avatar or make changes to the App language and colours.
Once you fully exit the App, the Demo version will be closed.
