Abstract
Aspects and features of this disclosure include operating an RFID reader to identify targeted tags and background tags from among a population of RFID tags. The background tags are then monitored by reading the background tags at a background rate and the targeted tags are tracked by reading the targeted tags at an enhanced rate. The enhanced rate is significantly greater than the background rate. The tags from a large population can be segregated into the two subpopulations based on read measurements stored in a tag database. A tag may become 'targeted' by moving towards or appearing near a portal of interest. Tag detection, and therefore an alarm message or some other desired result, can be provided quickly due to the higher, enhanced read rate being applied to the targeted tags.
