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?
There may be phones that allow you to do this and there are also smart rings you may be able to use by cloning the card with a proxmark 3, a flipper 0 or other similar devices.
I see that my phone should support encoding NFC tags. I’ll order a cheep ring and see if it works. Thanks.
I’m still curious though, why cannot phones produce that signals on their own? Isn’t this what they do with payment apps?
NFC ≠ RFID
Payment apps are NFC
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.
It’s doable. Read thoroughly and you’ll be good to go
Do you have a starting place? All I’ve found is instructions for copying NFC tags.
Certain systems have clone card detection these days so you might run into issues
