The reason my iPhone surfaced my Starbucks Card last week was because it detected I was near the coffee shop. It can do this with GPS, Wi-Fi or both and it’s pretty handy. Apple can take things a step further, though, with iBeacon.Perhaps the wallet app or Passbook pops up a coupon or other promotion when iBeacons recognize I’m actually just outside or in a store. Better yet, since iBeacons can pinpoint indoor proximity to a more precise level, my iPhone could realize when I’m in the checkout line of a store. The wallet app or store card for that particular location could magically surface just the right card so I don’t have to fumble around with a dozen piece of plastic in my physical wallet. Think of it as a contextual experience when paying: The right time, place and card.
