    For cases 3S, 4S, 3E and 4E, write the method to handle incoming data. The system ensures the synchronization between all the concurrent calls to this method, and that only one APDU will be sent at a time, irrespective of the number of TPDUs that might be required to transport it to the SE. This class encapsulates a command APDU, ensuring its validity at construction-time, and guaranteeing it remains valid for the lifetime of the object.

    It can be either a logical channel or the basic channel. Query the encoded length in bytes of the command data Lcif present.

    If there's really a need for the extended APDU commands, they can at all, but since most Android-phones also don't support extended APDU. I am using jmrtd api in Android platform, but it is not implement ATR reading I wondering is it possible to read ATR by sending a APDU command directly.

    As I read in ISOif cards support extended length it should be. I need to get ATR data to check the card support extended APDU or not.

    I've found this topic, and I have some question Android/NFC: read.
    The system ensures the synchronization between all the concurrent calls to this method, and that only one APDU will be sent at a time, irrespective of the number of TPDUs that might be required to transport it to the SE.

    The channel shall not be closed even if the Secure Element answered with an error code. In order to install or write anything on the embedded SE, you will need the GP secure channel keys.

    The authentication with the German eID card uses the „Extended Access Control“ order to be verified with a corresponding VERIFY CERTIFICATE command according On Android-based smartphones the supported APDU-length can be .
    If no further Applet exists with matches to the partial AID this method returns false and the already selected Applet stays selected.

    In other words, this is another take on everyone's except for widget authors As all applications, the Card Manager is also identified by an AID, so our first step is to find this out. Query the first parameter byte for the command. Le field present, but no Lc or command-data fields. Thread safety: This class is immutable, and thus fully thread-safe post-construction.
