What does rfid look like?

RFID (Radio Frequency Identification) typically consists of two main components: a tag and a reader. The tag is often a small, flat device, which can be as tiny as a grain of rice, and contains a microchip and an antenna. The reader is usually a larger device, often resembling a handheld scanner or a fixed installation, and emits radio waves to communicate with the tag. Together, they enable the wireless exchange of data for tracking or identification purposes.
