I'm using a NFC card reader (connected via USB) and whenever I put a tag on top of it the LED blinks and it makes a noise. I have been searching for the service file that is launched when the tag is put on the reader, but I haven't been able to find it (I understand that's a service, right?). Do you know where these files are stored? are they part of the system or are they located on the readers drivers?

  What's on the NFC tag? ... PGP keys? x509 keys? something else? ... if PGP keys, then gpg --card-status should show whether the NFC tag is within range... The card reader itself requires a kernel driver and a daemon ... GPG uses scdaemon... The card reader and card type need to be known before addressing the software stack required.

  Are you asking about what generates the noise?

  If the noise comes from the actual NFC reader, then it's probably a hardware feature of the reader itself: it might happen anytime the reader is receiving power and detecting a tag within reading range, whether or not the connected computer has any drivers loaded. Please run lsusb, identify the line describing the NFC reader, and add it to your question. That would describe the make and the model of the reader, and then it would be possible to find out what features its driver has.
