Abstract
In an aspect, the present disclosure includes a system for interrogating a person exiting a store. The system comprises one or more pedestals positioned to define an exit portal leading to a point of exit, one or more mmWave sensors, fixedly positioned near the point of exit, configured to receive one or more reflected mmWave beams from a person approaching the point of exit and triggering an interrogation of a security tag; and one or more security tag readers, fixedly positioned with the one or more pedestals, configured to read data from the security tag passing through the exit portal
Claims20
A system for interrogating a person exiting a store, comprising:
- one or more pedestals positioned to define an exit portal leading to a point of exit;
- one or more mmWave sensors, fixedly positioned near the point of exit, configured to receive one or more reflected mmWave beams from a person approaching the point of exit and triggering an interrogation of a security tag;
- and
- one or more security tag readers, fixedly positioned with the one or more pedestals, configured to read data from the security tag passing through the exit portal in response to triggering the interrogation.
A method of interrogating a person exiting a store, comprising:
- transmitting one or more interrogation mmWave beams to a person approaching a point of exit;
- receiving one or more reflected mmWave beams from the person;
- triggering an interrogation of a security tag in response to receiving the one or more reflected mmWave beams;
- and
- reading data from the security tag.
A non-transitory computer readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:
- cause one or more mmWave transmitters to transmit one or more interrogation mmWave beams to a person approaching a point of exit;
- cause one or more mmWave sensors to receive one or more reflected mmWave beams from the person;
- triggering an interrogation of a security tag in response to receiving the one or more reflected mmWave beams;
- and
- reading data from the security tag.
