(Error Code giving the reason for the failure.)
Byte 2: SW1
(Value of SW1 returned by the Card (SW1SW2 is 0000 if SW1 SW2 not
available))

(Value of SW2 returned by the Card (SW1SW2 is 0000 if SW1 SW2 not
available))
Byte 4: RF State Code
(RF State Code indicating exactly where the error occurred in the Reader-
Card transaction flow.)
TLV Data
Variable
Refer to the Activate Response TLVs.

Get Transaction Result (03-00 and 03-40)
NOTE:
03-00 is a legacy command, applicable to non-encrypted transactions only.When EMV
encryption ON or MSR/MSD encryption ON, if Data encryption Key is loaded, 03-00 will be
disabled. 03-40 is a unified command for both non-encrypted and encrypted transaction.
Use this command when the ViVOpay reader is functioning in “Auto Poll” mode. In this mode
the reader does not wait for an
command to start polling for a card. It is
