Beacon technology is practically revolutionising the customer retail experience by bringing a whole new dimension of digital interaction between you and your customers. What is iBeacon and why is it better than NFC? iBeacon is, for those who may not know, a version of BLE (Bluetooth Low Energy) software which was introduced by Apple starting version iOS 7. What we have seen in the past couple of months is that a whole new breed of developers and firms are coming with their own version of software to not only collect details of their customers but also proactively guide them in order to develop stronger and lasting relationships with their customers. Technologically, Beacon tags have a reach of 70 meters or so and really beat the NFC (Near Field Communication - which I mentioned in my Fog Computing article sometime back), thereby giving it an edge to maximise its reach. Also its less intrusive since there is no scanning necessary.
