摘要： PROBLEM TO BE SOLVED: To provide a memory tag performing retransmission of data independely from a retransmission request of data. SOLUTION: The memory tag 30 comprises a resonant circuit part 32 and a non-volatile memory 34. The resonant circuit part 32 is operated, in response to a reader signal received from a reader 31, to provide power to the memory 34. The tag 30 is operated to read the memory and transmit data stored in the memory 34 in response to the signal from the reader 31, and the data are stored in the memory in a plurality of data units 46. Each data unit 46 has a sequence number 47. The memory tag 30 is operated to store the sequence number 47 of the data unit 46 to be transmitted in a register 48 in the non-volatile memory 34. When power is supplied to the memory 34, the data units 46 are transmitted in sequence, and the first data unit 46 to be transmitted is determined depending on the stored sequence number 48.

摘要： PROBLEM TO BE SOLVED: To provide a detector which easily detects the position of a tag even if a memory tag is miniaturized and relatively low power. SOLUTION: The detector for detecting the presence of the memory tag comprises a radio frequency source operable to generate a radio frequency signal, and a detector resonant circuit which is connected to the radio frequency source and includes an antenna. Moreover, it comprises a power monitor for responding to the power of reflected signal returned from the detector resonant circuit. The power monitor is operable to generate an output in response to the power of the reflected signal, and detects the presence of the tag near the antenna from a decrease in power of the reflected signal.

摘要： A mobile networkable device eg. mobile phone or PDA (50), includes a reader (60) adapted to read a memory tag (20) on an article (2), such as a printed document. In use, the reader (60) reads the memory tag (20) on the article (2) to obtain co-ordinate data for a location B of a place mentioned in the article. The device (50) communicates the co-ordinate data of destination location B to the server system (76) in addition to the location of the device (50). The device (50) then receives route data from the server (76). The route (and/or map) data received is dependent on the location of the device (50), and location of the destination B.

摘要： This invention provides a processor for writing data contained in payload data of a data packet to memory. The processor may, in some embodiments, be a central processing unit of a memory tag. The processor does not include a write buffer. The processor may comprise a first register adapted to latch first data corresponding to a segment of the payload data; and a second register adapted to receive second data from the payload data to enable the validity of the data latched into the first register to be established before data is written to memory. A memory device, a method for writing data contained in payload data, a data packet, a method of writing data into a non-volatile memory and a memory tag may also be provided.

摘要： A memory tag (for example an RFID tag) comprises a memory containing stored content and a transponder which enables wireless electromagnetic communication. A client interrogates the memory tag, receives content from the memory tag by wireless electromagnetic communication in response to the interrogation, and stores the content. The client then sends a release request to an authoriser. If appropriate, the authoriser then sends a release confirmation to the client in response to the release request, and the stored content can then be released in response to receipt of the release confirmation. The specific embodiment is of a memory tag storing encrypted content, and where a decryption key is provided to allow decryption of the content which has been downloaded from the memory tag. The stored content may include a cost indication, and the release request may be in the form of a Short Message Service (SMS) message.

摘要： A memory tag in the form of a radio frequency identification tag (RFID) includes a memory storing data, an operating program and a current password. The memory tag is operable, in response to a read signal 64 from a tag reader requesting data 67, to run the operating program to check the read signal for inclusion of a token 66 dependent upon the current password. If the token is identified within the reader signal, the memory tag is operable to read the requested data and transmit it to the reader 72, 73. If the current token is not identified within the reader signal 71, the memory tag does nothing so as to avoid announcing its presence in any way. The token may be the password itself or a derivative of the password. The tag password may be set at the time of manufacture, or updated after each communication from the tag to the reader. Alternatively the tag receives a new password from the reader after transmitting the requested data. The current token and new passwords may be sent in encrypted form.
