According to a report, three-quarters of America’s smartphone owners use their devices to retrieve information related to their location. Such location data is promising to advertisers. They can begin sending customers so-called hyperlocal advertising, tailored not just to the city, but to a particular city block. The technology is called “geofencing”, which has been used for years in the ankle bracelets worn by accused criminals under constant surveillance. A judge might grant a criminal suspect permission to go to her job, her church and her local supermarket, with each approved location plugged into the court’s computer system. Data from the ankle-strapped GPS could confirm that the suspect was staying out of mischief or send a warning to police when she went to a prohibited location. Geofencing also has other uses, for example for parents who want to know about their children’s whereabouts. The service retrieves location data from a child’s phone and sends a message whenever the child arrives at home or at school or leaves again. When marketers build a geofence, they have no desire to restrict customers’ movements. The goal is to detect people’s close approach to a nearby business that is looking to make a sale, so the company can ping customers with a text message urging them to buy. Because marketers realise that nobody wants a constant stream of text messages, a policy of “frequency capping” is practised. Customers generally get no more than five messages a week, even if many other attractive deals come within range. Still, geofencing is rarely used by advertisers nowadays. The technology requires constantly recalculating the phone’s position, which shortens battery life quickly. Yet, even if geofencing becomes more energy efficient, it might still not be a sound strategy for selling many consumer products. As psychologists found out, valuable things are usually not consumed spontaneously. It is highly unlikely that a customer, alerted by his phone that a half-price sale on expensive consumer technology is taking place in a store nearby, will act upon sudden impulse and seriously consider the offer. Even at the lower price, such items will cost hundreds of dollars and are thus the sort of purchase consumers think about and plan for.
