Hi,
a lot of bank institutes are combined to a special group like the Cash Group (Deutsche Bank, Dresdner Bank, Postbank)…
I think it would held to add a tag wich represents this information so you can search an ATM which is a meber of your bank group.
Then you’ll know where you can get your money for free without paying fees.
Of cause, I could create this tag for the atm near me but I think there should be created a standart tag at the wiki.openstreetmap.org/wiki/Map_Features page…
How do you think about this idea ?
