The pin code is a great idea, that's what my bank uses for signing operations inside their app. You have username and password to access your account, where you can see your balance and movements but if you want to do something sensitive like transfer funds to another account you have to enter some digits of an 8 digit pin (for example, digits 1, 5, 6 and 8, changes every time).
