Abstract
Various embodiments illustrated herein disclose a method. The method includes receiving, by a first radio-frequency identification (RFID) tag in an RFID reader, a first interrogation command from another RFID reader. The method includes transmitting, by the first RFID tag in the RFID reader, a first response signal to the other RFID reader in response to the reception of the first interrogation command. The method further includes transmitting, by a processor in the RFID reader, a second interrogation command to one or more second RFID tags, where the transmission of the second interrogation command is concurrent to the reception of the first interrogation command or the transmission of the first response signal.
