The NFC Field Detector card is a must-have for the NFC professional. Three LEDs light up when an NFC field is detected. The card also includes the ST25TV02K chip with 256 bytes of user memory. With this card you'll never need to guess the location of your device's antenna. The intensity of the light from the LEDs will brighten and dim with the strength of the NFC field.
Demonstrate the concept of energy harvesting with this field detector card. The LEDs are powered by the energy transmitted by the reading device. No batteries inside. Hold your NFC phone up to this card and watch it light up!
