Hi, hate to bother your extremely good work, but after uploading the last code for web and sd. it keeps telling me error writing to SD master.dat

I have tried your code and set a master card at the beginning but after registering a card and leaving the master program and re scanning the master card it shows up as invalid card. here is my event log.

i used MFRC_nested_attack to recover the key but i think it works only on "A Key"

here how it looks

4475A2D4224578778800------------

is there someway to recover the "B Key" with MFRC_nested_attack

hi there, treid to compile today using the Arduino IDE but gut this error:

\RFID522-Door-Unlock-master\EEPROM\EEPROM.ino: In function 'boolean checkTwo(byte*, byte*)':
\RFID522-Door-Unlock-master\EEPROM\EEPROM.ino:404:16: warning: NULL used in arithmetic [-Wpointer-arith]
   if ( a[0] != NULL )    // Make sure there is something in the array first

Other useds came aross this problem, too so i guess it not necessarily related to my machine? https://www.himix.lt/arduino/arduino-and-rfid-reader-mfrc522-for-door-unlock/

RFID door unlock

I need to use the mega for the project that I have and it won't write a tag to the SD card but writes a master card no issue.
thoughts?

I did everything how it should be and wired it up. The RFID Reader just normal and the MicroSD at the ICSP Header and D4. The microsd and rc522 are working good alone but not together.

After a power down the data stored in the EEPROM is lost. How can this be prevented ?

Thanks

I want to open 2 doors but different admins to add multi levels
if i want to open door 1 i open it with user from admin 1
if i want to open door 2 i open it with user from admin 2
if i want to open door 1 + 2 i open it with user from admin 1 + 2

I hope I will not be told Arduino can only open its own sketches yet again help me if you know why?
Thanks
