If not an RFID then by Modulation. If it can be modulated you can communicate with it. For example https://www.instructables.com/id/Send-Music-over-a-Laser-Beam/

You talking about RFID right? Well the RF stands for Radio Frequency. The coils not only induce a current to activate the tag but they transmit data like any other wireless antenna does. Look up RFID protocol to learn how the system handles communication.
