I am developing a product and I would like to integrate an NFC chip into my system.
I want to send an URL to my laptop and at the same time turn on LEDs on my product with an NFC chip.
At first to do experiments, I took a PN532 chip and an arduino nano, I followed tutorials and I can read the UID of my phone (which changes with each scan I do not know why ??)
but impossible to use the PN532 as a simple tag my phone does not even recognize it.
How can I do this?
Do I use the right material? maybe another NFC chip is more convenient? Which shield should I work with?
Thank you in advance for your time.
Have a good day !
