Appendix B ARPC Response from Online Processing (EMV Only)

This section gives the format of the data for Command 0x07::0x03 - EMV L2 Online Processing Result. The host sends this command to the device in response to Notification 0x07::0x83 - EMV L2 ARQC Message. The data is a TLV object with the following contents:

F9	var	Container for MAC structure and generic data	T	R
/DFDF54	var	MAC KSN	B	R
/DFDF55	01	MAC Encryption Type	B	R
/DFDF25	var	Device Serial Number (IFD Serial Number)	B	R
/FA	var	Container for generic data	T	R
//70	var	Container for ARPC Response	T	R
///8A	02	Authorization Response Code · “00” = Approved · “10” = Approved · “11” = Approved · “05” = Declined · “51” = Declined · “Z3” = Declined	AN	R
///91	var	Issuer Authentication Data	B	O
///71	var	Issuer Script Template 1 As defined in EMV Integrated Circuit Card Specifications for Payment Systems 4.3. The host may include as many instances of this parameter as needed.	B	O
///72	var	Issuer Script Template 2 As defined in EMV Integrated Circuit Card Specifications for Payment Systems 4.3. The host may include as many instances of this parameter as needed.	B	O

Padding to ensure the length of data, starting at the first byte (F9), and ending with any additional padding, is a multiple of 8 bytes. This is a requirement of using the CBC-MAC algorithm.

Four byte CBC-MAC. Currently the device does not check this value. The host should set the value to 0x00000000.
