Class TargetType

java.lang.Object
  javax.microedition.contactless.TargetType

public class TargetType
extends java.lang.Object

This class collects the contactless target types supported by the Contactless Communication API. New target types can be added to this class only in a new version of this specification. The application developers must take into account that the list of target types may be extended in the future.

The NFC Forum data formatting (NDEF) gives an application level categorization for the target types. Therefore each NDEF_TAG is also categorized as either RFID_TAG or ISO14443_CARD on the physical level. Information about the connections that can be opened to the physical target is provided in the TargetProperties.getConnectionNames() method.

Field Detail

ISO14443_CARD

public static final TargetType ISO14443_CARD

ISO14443-4 compliant smart card accessed with APDU commands defined in ISO7816-4. Communication with this target may be done using ISO14443Connection.

NDEF_TAG

public static final TargetType NDEF_TAG

A tag that contains NFC Forum formatted data. NFC Forum specifies a list of mandatory physical tags and they all must be detected as NDEF_TAG by the implementation of this API. If the physical tag type is other than one of the mandatory tag types defined by the NFC Forum, and the API implementation support the NDEF formatted data for that physical tag type, it must be detected as NDEF_TAG.

NDEF formatted data may be accessed with NDEFTagConnection.

RFID_TAG

public static final TargetType RFID_TAG

General RFID tag containing data in a proprietary format. Communication with this target may be done using PlainTagConnection or one of the possible target-specific classes provided by the API implementation.

VISUAL_TAG

public static final TargetType VISUAL_TAG

General visual tag. Communication with this target may be done using VisualTagConnection.
