Visa launches iOS app that serves location-based offers
Those who own Visa Signature cards will also receive special Signature offers in addition to the standard offers that everyone else gets. The offers can be redeemed either online or at physical retail locations, and they are stored inside the app. You can also get a map and directions to ATMs in your immediate vicinity, as well as nearby retailers where you can redeem offers.
Visa also has an Android application out, but participation in the Android program is currently limited to select US Bank debit cardholders, whereas the iOS app is free and usable by all US-based Visa account holders.
