The response data that is received from the PICC. The contents of the
response depend on the application residing on the PICC and are out of
the scope of this document.
For SRED device, the Raw Data being received from the card/device by the reader will be
checked for sensitive data elements using rule in “Secure Pass-Through Function”. If found,
and it has not been established that this transaction belongs to an AID or BIN on the White
List, the Command will return a Parameter Not Supported error (0x06).

Example: Sending a HALT Command to a Type A PICC
Assuming that ViVOpay has been put into Pass-Through Mode, a Type A PICC has been
detected using the Poll for Token command, and the terminal application has completed the
transaction with the card, an ISO 14443 HALT command can be sent to the PICC using the
command. Given below is a log of the command and data that the
terminal would send to ViVOpay and also the responses that may be received from ViVOpay.
The following serial data may be exchanged between a terminal/PC and a ViVOpay reader:

High-level Halt Command (2C-09)
This command instructs the ViVOpay reader to send a HALT command to the card and can be
used for any Type A or Type B card. This command can only be used after the reader has been
put in Pass-Through mode and the “Poll for Token” command has indicated that a Card is
present.
