NFC Tags and Door lock

I am trying to build a scene/routine with the NFC tag to trigger the Tinxy Lock. Have a couple of queries

  • I have read some forums of IFTTT or tasker or other tools that helps with utilizing the nfc tag and creating a routine. However can any mobile phone trigger the NFC tag?
  • If only a particular mobile phone triggers the tag, is there any way to have multiple (selected) phones trigger the nfc tag. This is primarily because it triggers the lock and the tag will be outside on the door and visible to anyone passing by.

you could use the above module to read NFC and add to the switch of the lock controlled offered by us. It would require some electronics/ Arduino knowledge though
