In some implementations, a system may receive, from a motion sensor, an inactivity indication that indicates a period of inactivity within a physical environment. The system may store, in a data structure, identifiers of a plurality of RFID tags that a tag reader read during the period of inactivity. The system may receive, from the motion sensor, a motion notification that indicates a period of activity within the physical environment. The system may cause the tag reader to collect an identifier of an RFID tag in the physical environment during the period of activity. The system may determine, based on the identifier and the identifiers of the plurality of RFID tags, a movement status associated with the RFID tag during the period of activity and perform an action associated with the movement status of the RFID tag.
