| Zusammenfassung: | The Radio frequency identification device(RFID) reader has a RFID chip (112), a bearing surface (102) for a side of the document and another bearing surface (104) for another side of the document. An antenna (124) is arranged underneath the former bearing surface, and another antenna (128) is arranged underneath the latter bearing surface. The antennas are formed for inductive selection of the RFID-Chips on a nearby field. An INDEPENDENT CAIM is also included for a method for tuning of antenna resonant circuits. |
