There is in quantum computing lol
True, but the options available to a qubit still donāt allow for ānot existingāā¦ even if schrodingers bit is superpositioned.
Well I just bought 3 potential control boards from ali to try out
1 very similar to the xac, but a blue and pcb slightly different board layout, hopefully a different manufacturerā¦ and not running ripped off firmware
2 double antenna xac, very different board layout, hopefully not running the same firmware
3, very similar to xac but running 13.56 with a daughter board on the antennaā¦
Give shipping a month or so
Anything that fails with the exploit Iāll plan to return, and I think Iāll leave a public review posting about itā¦
It may be the only thing that might get a response from them
I never would have written code that mapped the UIDs in the EEPROM simply by offset without any āin useā flag. Crazy. Looked into the processor they use and itās a clone of an ancient 8051. Was hoping it was something more modern where we could just write our own code. Iām not familiar with the 8051 or itās toolchainā¦
Mind getting links to the second 2? Sounds kinda interesting with 2 input antennas, also hf is hf.
Edit: nevermind I think I found it

This one both ācolorsā there only an icon for the 13.56 version
Did you try out those boards?
Yep, I swear I posted that I tested them,
The second link above the blue board single antenna didnāt have the exploit,
However it was noted that they only check the first half? Or 2? Bits I forget the details they are on here somewhereā¦. But a weak password is still better than essentially 0000000 as a master password
Is this still an issue with the xAC v4?
The v4 should not have this vulnerability.
Read post below.
sigh It does presently. We are working to resolve this. The v3 did not. Two steps forward, one step backā¦ Iāll post here when I get an update.
