    摘要： A data carrier (1) for contactless communication with the communication station comprises firstly a receiving stage (3) for receiving a request signal (IS), secondly a storage facility (16) for storing at least two items of status information (EASB1, EASB2), thirdly a readout facility (15) for reading out one item of status information (EASB1, EASB2) at a time in response to receiving the request signal (IS), fourthly a processing circuit (18) for processing the status information (EASB1, EASB2) read out in each case so as to create a transmission signal (MCRS) suitable for transmission to the communication station, fifthly a recognition facility (22) for recognizing the status information (EASB1, EASB2) read out in each case, and sixthly a control connection (25) between the recognition facility (22) and the processing circuit (18), such that the processing circuit (18) can be influenced via the control connection (25) into altering a transmission parameter for a transmission signal generated by the processing circuit (18) as a function of the status information (EASB1, EASB2) recognized and readout in each case.

    摘要： As an RFID interrogator transmitting a command depending on a collision situation and a control method thereof, the RFID interrogator includes a collision diagnosis unit that analyzes data of a received signal received during a receive time in correspondence with a transmitted signal from an RF communication unit that can transmit and receive signal to and from one or more tag, verifies whether or not a collision occurs in the received signal, and diagnoses a collision type depending on an analysis result of the data of the received signal; and a collision resolution unit that can retransmit a command to the tag through the RF communication unit depending on the collision situation on the basis of whether or not occurrence of the collision or not and the collision type that are received from the collision diagnosis unit.
