Mif.VirtualCardSelect
Command is only supported by MIFARE Plus EV1 cards. Selected in
ISO14443-3 mode the VCSupportLastISOL3 command is executed.
Selected in ISO14443-4 mode the IsoSelect command is executed
If the card answers in the latter case with a Payload (UID does
not match or authentication with VCSelection is mandatory) the
reader executes an additional ISOExternalAuthentication command
Properties
- Command code: 0x101A
- Command timeout: 100 ms
- Possible status codes: General status codes, Mif.ErrNoTag, Mif.ErrAuth, Mif.ErrKey, Mif.ErrCode , Mif.ErrCmd, Mif.ErrNotauth, Mif.ErrKey, Mif.CondNotvalid
Parameters (request frame)
| Name | Type/Size | Description | |
|---|---|---|---|
| - | Bit mask (8 bits) | - | |
| RFU | Integer (bit mask area 0xC0) |
Zero padding |
|
| ForceVcsAuthentication | Boolean (bit 0x20) | Forces authentication to a virtual card. A card without encryption returns Mif.VcsAndProxCheckError | |
| UseExtVcSelectKeys | Boolean (bit 0x10) | Authenticates to a virtual card. A MAC and an encryption key have to be specified. Use (external) Virtual Card keys given as command parameter. | |
| DiversifyMacKey | Integer (bit mask area 0x0C) |
Diversifies VC Mac key.
Remarks for use of divinput: VC-UID is obtained by decryption of the card response. If VC-UID is concatenated with divinput the input wil be limited to 31 bytes. |
|
| DiversifyEncKey | Boolean (bit 0x02) | Diversifies VC Encryption key | |
| UseVcSelectKeys | Boolean (bit 0x01) | Authenticates to a virtual card. A MAC and a encryption key has to be specified. Use keys stored in CryptoMemory or SAM. | |

|
|
| Optional field, condition: (DiversifyMacKey == 1) or (DiversifyMacKey == 2) or (DiversifyMacKey == 3) or DiversifyEncKey | |||
| Length of DivData | Integer (8 bits) |
