Is it possible to increase the intensity of the NFC shield a little bit more. I read some documents online saying that the nfc shield (based on the nxp pn532) can reach up to 10 cm length. Seeedstudio’s antenna seems to reduce the intensity that can be emitted for the pn532. Is that possible to attach a different antenna in order to reach at least 10 cm of length?
Yes, as the PCB space limited, we design a small antenna for our NFC Shield V2.0.
You can attach a bigger antenna(13.56MHz) to increase distance.
