British retailers are testing mannequins outfitted with VMbeacon technology from the startup Iconeme.

One of our Things to Watch in 2014, beacons have been popping up everywhere from airports to restaurants to museums. But the biggest pickup for these devices—low-cost transmitters that use Bluetooth to precisely track consumers’ mobile phones and send targeted content—has been among retailers. Now, British retailers including House of Fraser, Hawes & Curtis and Bentalls are testing mannequins outfitted with VMbeacon technology from the startup Iconeme.

A “smart mannequin” enables nearby shoppers with a related mobile app to get details about what it’s wearing and how to find the products in the store or buy them online. The big question is whether customers will be motivated to opt in; skeptics say the technology doesn’t yet provide enough real benefit.
