I am looking for a way to unlock door lock using NFC from phone as shown in these videos:

  1. https://www.youtube.com/watch?v=ISxnUqb5_8Y&t=65s
  2. https://www.youtube.com/watch?v=_IIDq5IS6I0
  3. https://www.youtube.com/watch?v=7jq_pOwf9bo

Initially I tried to figure out emulation of NFC card, but numerous posts state that it is not possible to emulate NFC from phones.

I tried emulation of Mifare Classic 1k protocol but it is not possible, I wanted to know which protocol these locks use so I can look forward to emulate it in apps. The reason I tried Mifare Classic is my client informed me his card is Mifare Classic. I am bit clueless here.

But the guys in the video are doing something, I wonder if it is possible with rooting phone. If yes, what emulation should be used?

It is possible in phone hardware, on Android as a normal developer you can do Host Card Emulation HCE on iPhone, Apple restrict that to themselves but they do support Passkit in Apple Wallet.

  • I tried emulation of Mifare Classic 1k protocol, but it is not possible, I wanted to know which protocol these locks use so I can look forward to emulating it in apps. It is for one of my clients and per him, his lock gets unlocked using Mifare Classic card. I have been trying to emulate it since couple of months now without luck. – Calvin Aug 08 '23 at 12:01
  • As per https://stackoverflow.com/a/76850393/2373819 most hardware won't emulate this propitiatory mifare format. – Andrew Aug 08 '23 at 12:27
  • Yes, I figured out that, by any chance you know how these guys make the door unlock using phones? – Calvin Aug 09 '23 at 06:10
