This provides an example of how beacons can be used to tie information to objects without any need for the user to do anything manually. Well, they probably had to start the exhibition app, but apart from that, just walk around and get information about the objects via their phones.

CliqTags is ideal for short term scenarios like this, as nothing needs to be developed per scenario, so lead time is very short, and verification is done in a jiffy. You only associate beacon IDs with content published via CliqTags. That content can be altered up until and even during an event.
If you arrange events, you can easily re-use the same beacons by reconfiguring the content. You can even keep the previous content as an archive, as beacon associations can be moved between different content.
