Returns a smart card communication protocol.

The protocols are defined like PROTOCOL_* constant field values.

Returns:

a smart card communication protocol.

getData

public byte[] getData()

Returns a copy of the data bytes in the response body.

Returns:

a copy of the data bytes in the response body.

getBytes

public byte[] getBytes()

Returns a copy of the bytes in this ATR.

Returns:

a copy of the bytes in this ATR.

toString

public java.lang.String toString()

Returns the string representation of object.
