Abstract
Provided are RF tags configured to access and/or control electronic media. These tags have a memory programmed to access a particular media source when polled by a RF transceiver connected with (preferably integrated with) a media player. The memory of tags may also be programmed with control parameters relating to the accessed piece of electronic media content. That is, the tags' memories may be written to with information relating to the tag user's preferences with respect to the piece of media, for example parameters such as volume or language for an audiovisual piece of media. Such preferences may be determined, for example, based on previous uses of the media. Or, the memory may register the place in the playback of the media when the tag is removed from the RF field of the RF transceiver so that playback may be resumed from that place when the tag again enters the field and is polled by the transceiver. RF media access and control systems incorporating such tags, and methods of using them are also provided.
