ReadBinary command

On receiving the ReadBinary command, the ST25TA02K 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.

Table 31 defines the R-APDU of the ReadBinary command.

Note:

For further return codes and definitions, refer to Section 5.6.2: Status and error codes.

For more details about NDEF file, refer to Section 3.1.3: NDEF file layout.

For more details about System file, refer to Section 3.1.4: System file layout.
