Get Serial Number (12-01)
Note:
This command can only be used after the reader has completed a
Set Serial Number
command.
The
Get Serial Number
command instructs the ViVOpay reader to return the 15-digit serial
number stored in its non-volatile memory. If a serial number has not been previously set in the
reader, this command fails with a
Command Not Allowed
error status. If the command frame
is not valid, the reader returns an error response frame.
