For NFC you use libnfc

https://github.com/nfc-tools/libnfc

Not sure about RFID but I took a look at the script and it appears it publishes messages on Mosquitto.

@Alok-Mishra if you have a build environment installed you use:

scripts/feeds install libnfc

Select it under "libraries" in make menuconfig, the run make

@crispyoz said in how to use from C/C++ code access NFC & RFID Expansion:

install libnfc

I just did that ,output of make says libnfc compile( make[3] -C feeds/onion/libnfc compile) , but I do not see any object being built ( I am searching for ''nfc'', using find )

[Alok Mishra]

I found it libnfc gets built it is under ./staging_dir/target-mipsel_24kc_musl/usr/lib/

-Thanks
