The company I work in switched to a new building, and we have those stupid doors with RFID cards on them. I’d be damned if I’m going walk with that I’m-working-in-hightech-company-card dangling of my belt. I wonder if there is a way for me to use my phone for credentials. I tried searching for it, and all I could find is ways for me to use the phone in order to copy the info from one card to another.

So is it somehow possible?

      True… I confused the term, but this makes my question even more relevant. Since I have to put the card on the reader, I guess that it is an NFC card, rather than RFID. Which means that I should be able to duplicate the signal with my phone. I think.

        Then again, what protocol does it use ? MiFare Classic then yes easy to duplicate.

        Other MiFares? It will be harder/impossible.

          I scanned the card using an app “NFC tools” It sais that it is manufactured by NXP and the protocol is MiFares 1k. Guess this hould work.

                My phone with NFC died a year ago so… Take what I say with a pinch of salt.

                If I remember correctly you can use NFC tools pro to emulate a NFC tag. It doesn’t always work. I think it’s in the write section then emulate.

                There are however hardware limitations on emulation because of sector 0. Maybe try to copy your NFC card to a blank NFC tag (get it cheap on eBay) then if it succeeds go toward emulation.
