Parameters

nRecNo

Type: byte

Absolute record number of record to be read. The first record usually has the record number 1.

nLength

Type: byte

Number of bytes to read from record. If this is zero, then the entire record is read.

Return Value

The complete response APDU is returned. The property CardResponseAPDU.IsSuccessful can be used to check whether the record was read successfully. The read record is available through the CardResponseAPDU.GetData method.

This method uses the following generic command APDU: CLA 'B2' RN '04' LE, where RN is record number byte and LE is the given length byte.

Note that this method does not work with ACOS1 cards which would need the byte value '00' in P2 instead of the correct ISO 7816-4 value '04' which is used here.
