Didn't realize you require login & pass to bank (registration didn't work on windows phone). While that's common in Germany, in Poland giving your login & passto 3rd party means that bank has no responsibility for any loss/fraud/anything if something goes wrong for whatever reason. This is breaching the term with the bank, that your login and password are confidential. In Poland a oauth like alternative for payments is used, where you end up on your bank website to confirm payment and then you go back to the merchant.
