I found out the AccessConditions "UserData": "05" so bit 9 is responsi
I found out the AccessConditions
"UserData": "05" so bit 9 is responsible for the door opening
but every door has "UserData": "05" as soon as I change it, the door does not open anymore and as soon as I enter "UserData": "06" the lamp lights up at the lock red at "UserData": "07" otherwise I get vom Lock no feedback.
I have read that the MIFARE Classic UserData bit 9 is not used for card encryption synonymous with snief processes, I see the "UserData": "06" bit 9 not
However, there are other numbers than in "UserData": "05" where the door opens
see the snief process no errors in the output
Already have many other letters from A-F tried but no result up to the "UserData": "06" where the lamp turns red
does anyone have a tip
"2": {
"KeyA": "A0A1A2A3A4A5",
"KeyB": "ABD42DD50E37",
"AccessConditions": "78778805",
"AccessConditionsText": {
"block8": "rdAB wrB",
"block9": "rdAB wrB",
"block10": "rdAB wrB",
"block11": "wrAbyB rdCbyAB wrCbyB wrBbyB",
"UserData": "05"

Good find!
User data byte, you can set ot to what ever you like if the sector trailer (ST) access rights allows it.
When simulation or on a magic uid card, its usually no limits. I have a hard time understanding your english so I am not sure what you actually is asking for.
btw, there is no garanti that the system changes the user data byte once you present your card to the reader. ie rewoking.
