Burst Mode is not allowed when MSR/MSD or EMV encryption is enabled and a data
encryption key exists.
When MSR/MSD or EMV encryption is enabled and a data encryption key exists, Burst Mode is
always OFF. In this condition, the reader will turn Burst Mode OFF automatically. If Burst Mode
is set to ON/AUTO EXIT through the
Set Configuration
(04-00) command, the reader will keep
Burst Mode OFF.
Note:
Burst Mode is disabled for SRED devices.

Payload Frame (On Successful Read)
On successful read ViVOpay sends a card payload frame to the terminal that always contains
frame type, status, and application type. The status always shows
Success (=00)
. The
application type can have any of the values defined in
. This is followed by the
track data. Only those tracks the reader was able to read from the card are sent. Each track
begins and ends with its start and end sentinel. After the track data, the reader sends two CRC
bytes. The details of the CRC algorithm used are given in
