A nearable can be a person, animal or object; To become a nearable, an object must have an electronic device that is both a transmitter and a sensor. Nearables are part of the “Internet of Things” (IoT) that allow objects to be online and tracked via the web. Nearables in MarTech can signal to a phone that a deal is available nearby.
