Abstract
A system that identifies multiple electronic tags includes a plurality of electronic tags attachable to a single object, each electronic tag having a non-overlapping readable region, and each electronic tag having a unique identifier. One or more electronic tag readers are configured to read the unique identifier of each electronic tag within the non-overlapping readable region. A computing system is connected to the electronic tag reader to provide digital services in response to reading the unique identifier of each electronic tag. In certain embodiments, the electronic tags can have integral sensor systems that detect, for example, light, location, acceleration, or other physical properties, allowing provision of particular digital services related to the sensed properties.
