ReadBinary command
On receiving the ReadBinary command, the SRTAG2KL reads the requested memory field
and sends back its value in the R-APDU response.
Before sending a ReadBinary command, a file shall be selected by using a Select
command.
The Response of the ReadBinary command is successful when the data to be read is within
the selected file (a); in other words, when the sum of P1-P2 and Le fields is equal to or lower
than the selected file length.
Table 30 defines the ReadBinary command.
