How does a NFC tag and chip work?
First, the reader sends commands and energy in the form of electricity to the NFC tag. The NFC chip of the NFC tag receives these through an antenna and is activated. Then the NFC chip interprets the reader's command and sends the necessary information back by antenna.
Since the chip is supplied with power from the reader at all times, it can interpret information and send it back again. This is exactly what wireless communication makes possible, which is what makes NFC so practical.
