Google announced last month that its Play Store will start notifying users of pertinent apps they might want to download based off their location. App developers will need beacons to trigger those notifications, and Estimote’s location beacons are one possible choice for them. Though those beacons were released only a few months ago, they're already being updated to include programmable NFC. Now they can be used for cardless payments or for prompting people to download an app when they put their phone to the beacon. The new beacons will cost $59 for three in a development kit, and they're still real pretty.
