In some embodiments, apparatuses, systems, and methods are provided herein useful to determining qualities of a line at a POS terminal in a retail establishment. In some embodiments, a systems comprises one or more RFID tags, wherein the one or more RFID tags are located near the POS terminal, an RFID reader configured to read signals transmitted from the one or more RFID tags, and a control circuit communicatively coupled to the RFID reader, the control circuit configured to receive, from the RFID reader, an indication of the signals transmitted from the one or more RFID tags, determine, based on the indication of the signals from the one or more RFID tags, properties of the signals transmitted by the one or more RFID tags, and estimate, based on the properties of the signals transmitted from the one or more RFID tags, a number of people in line at the POS terminal. 1. A system for estimating a number of customers in line at a point-of-sale (POS) terminal in a retail establishment , the system comprising:one or more radio frequency identification (RFID) tags, wherein the one or more RFID tags are located near the POS terminal;an RFID reader configured to read signals transmitted from the one or more RFID tags; and receive, from the RFID reader, an indication of the signals transmitted from the one or more RFID tags;', 'determine, based on the indication of the signals transmitted from the one or more RFID tags, a pattern of read periods and non-read periods, wherein an RSSI value of at least one signal transmitted from the one or more RFID tags is higher during a read period than the RSSI value of the at least one signal transmitted from the one or more RFID tags during a non-read period; and', 'estimate, based on the pattern of read periods and non-read periods, the number of customers in line at the POS terminal., 'a control circuit communicatively coupled to the RFID reader, the control circuit configured to2. The system of claim 1 , wherein during the read ...
