Recycling bins in London are monitoring the phones of passers-by, so advertisers can target messages at people whom the bins recognize.
The idea is to bring internet tracking cookies to the real world. The bins record a unique identification number, known as a MAC address, for any nearby phones and other devices that have Wi-Fi turned on. That allows Renew to identify if the person walking by is the same one from yesterday, even her specific route down the street and how fast she is walking.
The technology, developed by London-based Presence Aware, is supposed to help advertisers hone their marketing campaigns. Say a coffee chain wanted to win customers from a rival. If it had the same tracking devices in its stores, it could tell whether you’re already loyal to the brand and tailor its ads on the recycling bins accordingly. "Why not Pret?" the screen might say to you. Over time, the bins could also tell whether you’ve altered your habits.
"From our point of view, it’s open to everybody, everyone can buy that data," Memari says. "London is the most heavily surveillanced city in the world…As long as we don’t add a name and home address, it’s legal."
Renew would like to expand the technology to all of its recycling bins in London as well as those in New York City, Dubai, and Kuala Lumpur. In its test this summer, Renew installed the tracking devices in 12 of its London bins, most of them along a stretch of Cheapside, a busy street lined with retail stores:
The company still needs to sell retailers on the concept. Memari said he was working on a proposal for a bar that would install five tracking devices: one by the entrance, one on the roof, one near the cash register, and one in each of the bathrooms. That would allow the bar to know each person’s gender (from the bathroom trackers), how long they stay ("dwell time" is the official metric), and what they were there for (a drink outside or a meal inside). And targeted advertising for the pub could follow those people around London on Renew’s omniscient recycling bins.
Memari notes that MAC addresses, while unique, don’t reveal the owner’s name or other identifying information. He says companies like Facebook and Google collect more information about people. Of course, those sites have terms and conditions of use, even if few people read them. In theory, MAC addresses could be paired with other consumer data collection, like a supermarket loyalty card, which could reveal the person’s name. Memari says that would go too far.
