The working principle for ultra-high frequency RFID tags is based on radio wave backscatter.

Here are the steps:

1. The RFID reader emits a radio wave of specific frequency (in the UHF range, typically 860 to 960 MHz).

2. The RFID tag, which consists of an antenna and a microchip, receives this radio wave.

3. The tag uses the energy from the received radio wave to power the microchip.

4. The microchip then modulates the radio wave and reflects it back to the reader. This is known as backscatter.

5. The reader receives the reflected radio wave and decodes the information stored in it. This information is typically a unique identifier for the tag.

6. The reader can then use this identifier to look up associated information in a database, such as the identity of the object to which the tag is attached.
