RFID Portal Targeting

An RFID reader comprising:

• a processor;
• and
• a non-transitory storage medium associated with the processor, the non-transitory storage medium including instructions executable by the processor, that when executed cause the processor to:
• interrogate a population of radio-frequency identification (RFID) tags using an RFID reader;
• identify, based on the interrogation, a targeted tag and a background tag from among the population of RFID tags;
• monitor the background tag by reading the background tag at a background rate;
• and
• track the targeted tag by reading the targeted tag at an enhanced rate;
• wherein the enhanced rate is greater than the background rate.

Apparatus comprising a non-transitory storage medium, the apparatus further comprising:

• instructions disposed in the non-transitory storage medium for causing a processor to interrogate a population of radio-frequency identification (RFID) tags using an RFID reader;
• means for identifying, based on the interrogating, a targeted tag and a background tag from among the population of RFID tags;
• instructions disposed in the non-transitory storage medium for causing the processor to monitor the background tag by reading the background tag at a background rate;
• and
• means for tracking the targeted tag by reading the targeted tag at an enhanced rate;
• wherein the enhanced rate is greater than the background rate.
