Semi-Passive Tag

/

A Semi-Passive Tag is a medium cost tag containing a microchip, antenna and battery, but no transmitter. Semi-passive tags communicates with an interrogator via backscatter or inductive coupling, like passive tags, but have faster response times and greater memory capacity due to the battery. Semi-passive tags may also have longer read ranges than passive tags, but this is an ancillary benefit to the battery rather than its primary purpose.
