 ** ApplicationCryptogram **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-ApplicationCryptogram"></a>
The application cryptogram for the current transaction that is provided by the terminal during transaction processing.  
Type: String  
Length Constraints: Fixed length of 16.  
Pattern: `[0-9a-fA-F]+`   
Required: Yes

 ** MajorKeyDerivationMode **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-MajorKeyDerivationMode"></a>
The method to use when deriving the master key for the payment card.  
Type: String  
Valid Values: `EMV_OPTION_A | EMV_OPTION_B`   
Required: Yes

 ** Mode **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-Mode"></a>
The block cipher method to use for encryption.  
Type: String  
Valid Values: `ECB | CBC`   
Required: Yes

 ** PanSequenceNumber **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-PanSequenceNumber"></a>
A number that identifies and differentiates payment cards with the same Primary Account Number (PAN). Typically 00 is used, if no value is provided by the terminal.  
Type: String  
Length Constraints: Fixed length of 2.  
Pattern: `[0-9]+`   
Required: Yes

 ** PinBlockLengthPosition **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-PinBlockLengthPosition"></a>
Specifies if PIN block length should be added to front of the pin block.   
If value is set to `FRONT_OF_PIN_BLOCK`, then PIN block padding type should be `ISO_IEC_7816_4`.  
Type: String  
Valid Values: `NONE | FRONT_OF_PIN_BLOCK`   
Required: Yes

 ** PinBlockPaddingType **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-PinBlockPaddingType"></a>
The padding to be added to the PIN block prior to encryption.  
Padding type should be `ISO_IEC_7816_4`, if `PinBlockLengthPosition` is set to `FRONT_OF_PIN_BLOCK`. No padding is required, if `PinBlockLengthPosition` is set to `NONE`.  
Type: String  
Valid Values: `NO_PADDING | ISO_IEC_7816_4`   
Required: Yes

 ** PrimaryAccountNumber **   <a name="paymentcryptographydata-Type-EmvCommonAttributes-PrimaryAccountNumber"></a>
The Primary Account Number (PAN) of the cardholder.  
Type: String  
Length Constraints: Minimum length of 12. Maximum length of 19.
