A.1 Case 1

The command APDU is mapped onto the T=0 command TPDU by assigning the value ‘00‘ to P3.

The response TPDU is mapped onto the response APDU without any change.

A.2 Case 2 Short

It this case, Le is valued from 1 to 256 and coded on byte B1 (B1=‘00‘ means maximum, i.e. Le=256).

The command APDU is mapped onto the T=0 command TPDU without any change.

The response TPDU is mapped onto the response APDU according to the acceptance of Le and according to the processing of the command.

• Case 2S.1 - Le accepted

  The response TPDU is mapped onto the the response APDU without any change.

   

  R-APDU	Le bytes SW1 SW2
  R-TPDU	Le bytes SW1 SW2

• Case 2S.2 - Le definitely not accepted

  Le is not accepted be the card which does not support the service of providing data if the length is wrong.

  The response TPDU from the card indicates that the card aborts the command because of wrong length (SW1=‘67‘). The response TPDU is mapped onto the response APDU without any change.

   

  R-APDU	SW1=‘67‘ SW2
  R-TPDU	SW1=‘67‘ SW2

• Case 2S.3 - Le not accepted, La indicated

  Le is not accepted by the card and the card indicates the available length La.

  The response TPDU from the card indicates that the command is aborted due to a wrong length and that the right length is La: (SW1=‘6C‘ and SW2 codes La).

  If the transmission system does not support the service of re-issuing the same command, it shall map the response TPDU onto the response APDU without any change.

   

  R-APDU	SW1=‘6C‘ SW2=La
  R-TPDU	SW1=‘6C‘ SW2=La

  If the transmission system supports the service of reissuing the same command, it shall re-issue the same command TPDU assigning the value La to parameter P3.

   

  C-TPDU

  CLA INS P1 P2

  P3=SW2

  The response TPDU consists of La bytes followed by two status bytes.

  If La is smaller that or equal to Le, then the response TPDU is mapped onto the response APDU without any change.

   

  R-APDU	La bytes SW1 SW2
  R-TPDU	La bytes SW1 SW2

  If La is greater that Le, then the response TPDU is mapped onto the response APDU by keeping only the first Le bytes of the body and the status bytes SW1-SW2.

   

  R-APDU	Le (< La) bytes SW1 SW2
  R-TPDU	La bytes SW1 SW2

• Case 2S.4 - SW1-SW2=‘9XYZ‘, expect ‘9000‘

  The response TPDU is mapped on the response APDU without any change.

A.3 Case 3 Short

In this case, Lc is valued from 1 to 255 and coded on byte B1 (=‘00‘).

The command APDU is mapped onto the T=0 command TPDU without any change.

The response TPDU is mapped onto the response APDU without any change.

A.4 Case 4 Short

In this case, Lc is valued from 1 to 255 and coded on byte B1. Le is valued from 1 to 256 and coded on byte Bl (Bl=‘00‘ means maximum i.e. Le=256).

The command APDU is mapped onto the T=0 command TPDU by cutting the last byte of the body.

• Case 4S.1 - Command not accepted

  The first response TPDU from the card indicates that the card aborted the command: SW1=‘6X‘, except ‘61‘.

  The response TPDU is mapped onto the response APDU without any change.

   

  R-APDU	SW1=‘6X‘ SW2
  R-TPDU	SW1=‘6X‘ SW2

• Case 4S.2 - Command accepted

  The first response TPDU from the card indicates that the card performed the command: SW1-SW2=‘9000‘.

  The transmission system shall issue a GET RESPONSE command TPDU to the card by assigning the value Le to parameter P3.

   

  C-TPDU

  CLA INS=GET_RESPONSE P1 P2 P3=Bl

  Depending on the second response TPDU from the card, the transmission system shall react as described in cases 2S.1, 2S.2 and 2S.4 above.

• Case 4S.3 - Command accepted with information added

  The first response TPDU from the card indicates that the card perfomed the command and gives information on the length of data bytes available: SW1=‘61‘ and SW2 codes Lx.

  The transmission system shall issue a GET RESPONSE command TPDU to the card by assigning the minimum of Lx and Le to parameter P3.

   

  TPDU	CLA INS=GET_REPONSE P1 P2 P3=min(Le,Lx)

• Case 2E.1 - Le<=256, B1=‘00‘, B2B3 from ‘0001‘-‘0100‘

  The command APDU shall be mapped onto the command TPDU by assigning the value of B3 to parameter P3. The processing by the transmission system shall be according to case 2S.

   

  C-TPDU

  CLA INS P1 P2 P3=‘00‘

  • If the first response TPDU is 256 bytes of data followed by SW1-SW2=‘9000‘, this means that the card has no more that 256 bytes of data, and/or does not support the GET REPONSE command. The transmission system shall then map the response TPDU onto the response APDU without any change.

     

    R-APDU	256 bytes SW1=‘90‘ SW2=‘00‘
    R-TPDU	256 bytes SW1=‘90‘ SW2=‘00‘

  • If the first or subsequent response TPDU from the card is SW1=‘61‘, then SW2 codes Lx which is the extra amount of bytes available from the card (SW2 valued to ‘00‘ indicates 256 extra bytes or more), the transmission system shall compute Lm=Le(sum of the lengths of the bodies of the prviously received response TPDU(s)) to obtain the amount of remaining bytes to be retrieved from the card.

    If Lm=0, then the transmission system shall concatenate the bodies of all received response TPDUs together with the trailer of the last received response TPDU into the response APDU.

    If Lm>0, then the transmission system shall issue a GET RESPONSE command TPDU by assigning the minimum of Lx and Lm to parameter P3. The corresponding response TPDU from the card shall be processed

    • according to case d), if SW1=‘61‘
    • as above when Lm=0, if SW1=‘9=‘

  R-APDU	SW1=‘67‘ SW2
  R-TPDU	SW1=‘67‘ SW2
