What do nfc tags look like

This is very similar to the techniques used for wireless charging technologies, albeit much less powerful. The active devices, such as your smartphone, are responsible for generating the magnetic field.

This is done with a simple coil of wire, which produces magnetic fields perpendicular to the flow of the alternating current in the wire. The strength of the magnetic field can be adjusted by varying the number of turns in the wire coil, or increasing the current flowing through the wire. However, more current obviously requires more energy, and very high power requirements would not be desirable for use in battery powered mobile technologies.

The passive device works in the same way, just in reverse. There is always some power lost during transmission through the air, but over short distances the current generated is enough to power the circuitry in the NFC tag. This allows for a maximum transfer of energy across the air.
