- Using a phone to find the nearest ATM (according to MocoNews)
- Using a phone to interact with an ATM to prevent card skimming, PIN surfing etc
- Using a phone to pay for things at banks / checkouts
- Connecting an ATM to a mobile network as it's principal means of communication
- Remote control of an ATM with the phone's keypad
- Using phone to make voice calls
You have to assume that they decided to do some research into mobile banking, and before they started their patent lawyers specifically instructed them no to look at what anyone else was doing in the industry so that they could claim it was all internal innovation. Which is why they came up with a bunch of things people have been doing for years (1,3), extremely obvious applications of a mobile network as a means of reaching the net (4), ideas with limited utility which simply won't work in any usable way on handsets in the real world (5) and an idea which is the subject of a large number of startups and activity from other players like Visa (2).
It would be nice to sigh "Only in America could this patent be granted", but sadly given the type of company they are they'll probably try to bully smaller players into licensing something to establish precedent using their lawyers and political connections, and then generally strangle innovation in search of a quick buck. Ah well.
