I’m specifically looking to clone the Hop Fastpass transit card which is used in Portland, OR. According to my research, it uses a MIFARE DESFire EV1 chip. I currently have an xSIID and Apex Mega Spectrum implanted with an xEM on the way, but would probably purchase an additional implant for this purpose if needed.
My initial assumption was that the xM1 might do the trick, but I know that’s out of stock on the DT store - not sure if it’ll be back or not.
As far as i know, there is no way to clone a DESFire chip.
Your only option would be to get your own DESFire chip enrolled to the system.
But unless you know the persons in charge or are good at social engineering, chances of getting it done are small.
A xM1 is a magic Mifare classic chip, not a DESFire one
