It is not possible to read the Desfire part of a badge equipped with a 125 kHz and 13.56 MHz chip. #34

interesting issue... you might be right in your guess, can't think of anything else myself. desfire isnt cracked anyway, so emulating would not work, but still it is weird that it remains stuck. does this happen on official firmware too? please try on 0.99-rc |
I have just tested with the latest official firmware 99.1, and the issue persists. Here is a demonstration video: https://youtu.be/iGWESNVlHbA |
@Katsugami can you check on latest dev version? |
How can I install this version? |
I just tested it and it's still the same. |
I have a tag that was recognized as Mifare Desfire when I used the NFC read operation. After my last update, it is recognized as an iso14something and when I try to read it as Mifare Desfire the flipper does not recognize it. |
I have the same issue with Unleashed. I don't think it's linked to Momentum |
I am having similar issue. One transit card that I own can only be read as 4A Unknown and having SAK of 20, so it has to be DESfire or Plus. I found another person's reading of this type of card online done with NXP Taginfo confirming it's DESfire. However my flipper won't read it. |
This problem seems to have been resolved in OFW. I flashed my firmware to OFW 0.101.2 and have no issue reading the aforementioned DESfire card. It seems to be an older issue since NFC refactoring. |
Describe the bug.
Hello,
I have a badge that integrates a Mifare Desfire chip at 13.56 MHz as well as an EM4100 [EM-Micro] (125 kHz) chip in a single badge.
For reading the 125 kHz part, there's no issue, the Flipper reads it immediately. However, when trying to read the Desfire part, the Flipper remains stuck in continuous reading mode with the message "Don't Move".
I believe that the 13.56 MHz antenna of the Flipper might be disrupted because it is simultaneously powering both chips. The response of the badge at the 125 kHz frequency could be causing interference.
Do you think this can be corrected?
Reproduction
Another scenario:
3. Performing an additional action.
4. Selecting "Read Specific Card Type".
5. Choosing "Read MIFARE DESFire".
6. The application remains stuck on "Don't Move".
Target
NFC and RFID
