_MSR_DATA_RECEIVED structure

Description

This structure contains the data read from a swiped magnetic stripe card.

Members

`CardType`

Type of card that was swiped.

`Track1EncryptedDataLength`

The amount of encrypted track 1 data, in bytes, that is stored in Track1EncryptedData[MSR_TRACK_SIZE].

`Track2EncryptedDataLength`

The amount of encrypted track 2 data, in bytes, that is stored in Track2EncryptedData[MSR_TRACK_SIZE].

`Track3EncryptedDataLength`

The amount of encrypted track 3 data, in bytes, that is stored in Track3EncryptedData[MSR_TRACK_SIZE].

`Track4EncryptedDataLength`

The amount of encrypted track 4 data, in bytes, that is stored in Track4EncryptedData[MSR_TRACK_SIZE].

`Track1EncryptedData`

The encrypted data read from track 1 of the swiped card.

`Track2EncryptedData`

The encrypted data read from track 2 of the swiped card.

`Track3EncryptedData`

The encrypted data read from track 3 of the swiped card.

`Track4EncryptedData`

The encrypted data read from track 4 of the swiped card.

`Track1MaskedDataLength`

The amount of masked track 1 data, in bytes, that is stored in Track1MaskedData[MSR_TRACK_SIZE].

`Track2MaskedDataLength`

The amount of masked track 2 data, in bytes, that is stored in Track2MaskedData[MSR_TRACK_SIZE].

`Track3MaskedDataLength`

The amount of masked track 3 data, in bytes, that is stored in Track3MaskedData[MSR_TRACK_SIZE].

`Track4MaskedDataLength`

The amount of masked track 4 data, in bytes, that is stored in Track4MaskedData[MSR_TRACK_SIZE].

`Track1MaskedData`

The masked data read from track 1 of the swiped card.

`Track2MaskedData`

The masked data read from track 2 of the swiped card.

`Track3MaskedData`

The masked data read from track 3 of the swiped card.

`Track4MaskedData`

The masked data read from track 4 of the swiped card.

`Track1DiscretionaryDataLength`

The amount of discretionary track 1 data, in bytes, that is stored in Track1DiscretionaryData[MSR_TRACK_SIZE].

`Track2DiscretionaryDataLength`

`CardAuthenicationDataLength`

The amount of encrypted card authentication data, in bytes, that is stored in CardAuthenicationData[MSR_CARD_AUTHENTICATION_DATA_SIZE]. May include padding.

`CardAuthenticationDataAbsoluteLength`

The amount of card authentication data, in bytes, before encryption. This value may be used to remove padding on decryption.

`CardAuthenicationData`

Authentication data read from the swiped card.

`AdditionalSecurityInformationLength`
