We imagine K2 Bank providing an AppStore based on its APIs. Users will be able to give permission to third party service providers in a way you allow applications to access your Facebook or Twitter account today.
It will be possible to manage your accounts in different banks from a single user interface. Thanks to integration with online commerce instant payments will be possible and BankBot could help you shop by finding the best deal comparing hundreds of retailers.
BankBot can also live inside voice-controled smart devices like the Amazon Echo, which provides its own API for developers - smart home and smart banking mixed together.
