Mifare Plus open information

I collect here open info about mifare plus cards

https://www.jinmuyu.com/download/MIFARE … 0Guide.pdf

MIFARE Data/Value Blocks
MIFARE Sector Trailers                     |00 00h to 00 7Fh     | Sector 0 to 31
MIFARE Data/Value Blocks
MIFARE Sector Trailers                     |00 80h to 00 FFh     | Sector 32 to 39
MFP Configuration Block                   |B0 00h                   |Defines the number of unmaced commands as
                                                                                    |well as if plain communication is possible
Installation Identifier                        |B0 01h                  |Installation identifier as used in VC concept. The
                                                                                    |installation Identifier can be requested from NXP.
ATS information                               |B0 02h                   |The 'Answer To Select' Information
Field Configuration Block                  |B0 03h                   |Defines if Proximity Check is mandatory and if
                                                                                    |RandomID shall be enabled.

Keys

AES Sector Keys                              |40 00h to 40 3Fh     |AES Sector Keys from Sector 0 to 31. The second
                                                                                     | byte defines the sector number and which key
                                                                                     | (Key A or Key B) is used.
                                                                                     | KEY A = sector number muitiplied by 2
                                                                                     | KEY B = sector number muitiplied by 2 + 1
                                                                                     | E.g. Key A for sector 2 has the number: 40 04
AES Sector Keys                              |40 40h to 40 4F       |AES Sector Keys from Sector 32 to 39. The
                                                                                     |second byte defines the sector number and which
                                                                                     |key (Key A or Key B) is used.
                                                                                     |KEY A = sector number muitiplied by 2
                                                                                     |KEY B = sector number muitiplied by 2 + 1
Originality Key                                 |80 00h                    |The originality is personalised by NXP to the IC
                                                                                     |and cannot be changed. As the value of the key is
                                                                                     |not distributed outside of NXP, the authentication
                                                                                     |with this key is only possible with a special
                                                                                     |prepared SAM, supplied by NXP.
Card Master Key                               |90 00h                   |Can be used to change the Level Switch Keys as
                                                                                     |well as the MFP Configuration key.
Card Configuration Key                      |90 01h                   |Can be used to change the Field Configuration Block
Level 2 Switch Key                            |90 02h                   |Key to switch from Level 1 to Level 2
Level 3 Switch Key                            |90 03h                   |Key to switch from Level 2 to Level 3
SL1 Card Authentification Key            |90 04h                   |Key to do one additional AES authentification in security level 1
Select VC Key                                   |A0 00h                   | Key to perform Select VC
Proximity Check Key                          |A0 01h                  |Key to verify the Proximity Check
VC Polling ENC Key                           | A0 80h                  |Select VC Polling ENCKey
VC Polling MAC Key                           |A0 81h                   |Select VC Polling MAC Key
