摘要： This publication discloses an RFDD reading apparatus (1) and a method for the reading apparatus. The RFID reading apparatus comprises a transmitter (3), which is arranged to feed power to at least one RFED tag (2) in the vicinity of the RFID reading apparatus (1), and a receiver (4) operating on the frequency of the transmitter (3), so that the transmitter (3) and the receiver (4) are in operation simultaneously and the receiver (4) is arranged to receiver through a radio channel (7) a reflected signal of at least one RFDD tag (2) in the vicinity of the reading device. In accordance with the invention, the RFDD reading apparatus (1) comprises additionally means (Z2, 12, 13, 14, 20) for separating the payload signal arriving from the RFDD tag (2) from signals other than those arriving from the RFDD tag (2).

摘要： The invention is especially intended for visually impaired persons who are not able to read text printed on products or product containers. With the invented method at least a part of a product description, which corresponds to a bar code read and which is fetched from a product information database, is stored in at least one memory accessible to the terminal. After this, in response to a command ordered by a user of the terminal, the RFID identifier attached to the terminal is read and the product description is presented in speech format so that the information readable in the memory and the RFID identifier is utilized in the presentation. The terminal is preferably a mobile station equipped with a speech synthesizer. A visually impaired person can point with the terminal to one or more products and listen via an audio system of the terminal to the product descriptions related to them. When RFID identifiers are attached to the product, the products need to be pointed to as precisely when reading bar codes. The products are, for example, foodstuff or medicine.
