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?

    My work uses mifare cards if I recall it correctly. Using a simple nfc emulator app on a rooted phone, I could just clone the card instantly and use my phone to enter anywhere the card could.

    This had obvious big security repercussions. Someone with bad intentions could just walk past you and copy the card. So they added personalized pin codes to all cards, every poor sod in the company now has to touch their badge + give in a pincode for you pretty much all doors. They are currently in the progress of renewing the entire security system to upgrade the security of the cards. (at great cost :))

    So depending on the type of card used, it might be possible. I’ve tried it with many different security cards, it only worked with the one from my company. So it really depends on the type of card used.

    I think it was this app, but I’m not 100% positive. Haven’t rooted my new phone due to other security reasons, so I haven’t tinkered with it lately.
