The Find TCE app makes use of Bluetooth and Apple iBeacon technology. iBeacons are set up in locations and broadcast a unique Bluetooth ID. This ID can be associated with all sorts of actions, including opening webpages, playing videos, showing images, etc. We've kept it simple with text, images and a URL. Their range is fairly small (up to a maximum of around 15 metres in a relatively unobstructed environment), so they are ideal for close proximity information, advertising, etc. For this app we've set the range to 'near', which means around 5 metres.
For the iBeacons we're using Estimote Stickers. In the static locations the stickers have been stuck somewhere out of the way, whilst the people involved are simply carrying one around with them in a pocket or a bag. The app itself was designed using the Beacondo design environment, imported into XCode and finished off for the App Store. If you'd like to know more, please contact Gavin
