I was hoping to get some clarification on the implementation of the xM1+…
“The xM1+ is a Mifare S50 1k “Classic” compatible chip with a “Chinese backdoor” feature (if you want to call it that) which allows all data on the chip to be completely writable, regardless of any memory sector security, A/B crypto1 key values, or access control bit settings.”
“xM1 13.56mhz S50 (Mifare Classic 1K)
The xM1 is a high frequency 13.56MHz transponder based on the Mifare Classic S50 1K chip. This chip type is ISO14443A compliant but is not NFC compliant. The xM1 has 768 bytes of user programmable memory and also supports Crypto1 security features. The xM1 is supported only on some NFC devices which contain a reader chip from NXP. While the xM1 will work with any ISO14443A reader, including our PN532 reader, it cannot be expected to work reliably with all NFC devices. We supply the xM1 for people who have a specific need for this particular chip type.”
(apologies if this seems obvious, I am just an amateur at this stage)
Does this mean it would be possible to clone the information from a transit card to the xM1+ for example (if the technology is compatible). I live in Sydney and I remember reading that our Opal transport cards use Mifare technology. Thank you in advance for any answers.
