Power from the Magnetic Field: Basics of HF Band RFID (NFC) Tag Operation
We conducted an experiment to light up an LED by converting "magnetic field" into "electric power" through "wireless power transmission."
This time, we will confirm the basics of HF band RFID (NFC) tags through experiments. We will provide an experimental video to easily check "how cards without batteries," such as transportation cards, driver's licenses, and My Number cards, operate. Each card is equipped with an IC chip. To operate that IC chip, "power" is, of course, necessary. RFID tags receive and operate using that "power" non-contactly. In other words, it is "wireless power supply." In the case of HF band RFID (NFC) tags, the wireless that serves as the source of "power" is an "alternating magnetic field." *For detailed content of the column, you can view it through the related links.
