How is Beacon different from in-store WiFi? Except that WiFi works on any smartphone compared to Bluetooth Low Energy (used in Beacon) which is only available on a few latest models?.. (Google enabled full support of BLE on Android only
two months ago...)
Also, if I am in a "shop-dense" area (e.g. a shopping mall), guess how many competing Beacons will my phone see..
Last, but not least: why would any hacker call his "beacon"
anything else but, say, "Free coffee at Starbucks"?..
Once connected (via open API...), he can have some "fun" with your phone...
