Right now we want to quickly link to a few articles about the power of an exciting new implementation of Bluetooth LE: Apple iBeacons. An iBeacon can be any iOS device. The technology is built into iOS 7. Simply, an iBeacon is an iOS device emitting an efficient, low energy signal that basically says, "I am an iBeacon! Here I am!" along with a unique ID. Devices running apps that listen for these iBeacons will begin communication or perform some action when they find an iBeacon emitting a signal that interests them.
Card Table did not require the use of iBeacons, but it was a work project involving iBeacons that tipped us off to the power of Bluetooth LE and set us down the path of creating Card Table. Here are the articles:
