Mobile wallet integrated with multiple bank apps

I think integrating single mobile payment solution into multiple existing bank apps is interesting idea which has a future. On the one hand, we use mobile phones and we would like to use them as wallets for mobile payments, but we don't trust the mobile payments providers and don't like the eWallet apps. On the other hand, we already use bank apps and we (usually) trust the banks, but they fail to provide universal tool to process mobile payments. If we combine the two problems, there is a chance to get a viable solution.
