摘要： A radio frequency communication circuit includes an antenna having a conductor and a semiconductor chip having a lower substrate surface coupled with the conductor to pass data carried by radio frequency signals to a radio frequency communication circuit in an active layer on an upper surface of the substrate. Accordingly, communications are facilitated via the substrate and can alleviate the need to use through-substrate connectors and further facilitate placement of the chip on the antenna. Application to an RFID tag (300).

摘要： The invention relates to an RFID transponder device (1) configured for responding to a request of an RFID reader device (RW), by sending a response (UID) comprising information (FB) for encoding a feature set (FTRS) of the RFID transponder device (1). The invention further relates to an RFID reader device (RW) and to an RFID system comprising such RFID transponder device (1) and such RFID reader device (RW). The invention also relates to various methods. The invention provides an RFID system, which is more flexible towards introducing new RFID transponder devices (1) that are newly introduced to the market. The invention enables the introduction of such new devices using a sub-set of a prior defined feature set without requiring updating of the look-up tables of the RFID reader devices that are already on the market. This is achieved by directly encoding the feature set of the RFID transponder device (1) in the response, such as in a unique identifier (UID) of the device.
