Abstract
There is provided a system including a wireless tag reader, a wireless tag attached to an object, a non-transitory memory storing an executable code, and a hardware processor executing the executable code to transmit, using the wireless tag reader, an interrogation signal, receive, using the wireless tag reader, a tag signal from the wireless tag attached to the object, in response to the interrogation signal, the tag signal including a wireless tag identification uniquely identifying the wireless tag, determine a tag state associated with the wireless tag using a probabilistic estimate based on the tag signal received from the wireless tag, and determine an interaction state of the object based on the tag state of the wireless tag attached to the object.
