In a transmitting mode the controllers selectively change the state of the tag antennas to transmit data via backscattering the radio frequency signals.

A method in a system comprising at least one portable data carrier, an authentication server and at least one reading device of at least one service provider which is couplable to the authentication server. The data carrier is adapted to communicate contactlessly with the reading device and comprises a security marking which can be read contactlessly by the reading device and on the basis of which the data carrier can be authenticated by the authentication server. The method comprises the step of equipping the data carrier with a data-carrier management marking that encodes a piece of data-carrier management information and readable contactlessly by a portable terminal. The method includes contactlessly reading out the data-carrier management marking by a portable terminal, transferring the data-carrier management information encoded in the data-carrier management marking to the authentication server, and managing the data carrier in the system employing the data-carrier management information.

A method for vehicle-loading warehousing asset management based on an ultra-high frequency (UHF) radio frequency identification (RFID) path loss model, which includes the following steps. An electromagnetic wave is emitted by a tag reader. The electromagnetic wave is diffracted, reflected, and scattered when passing through a warehousing vehicle hood, and the electromagnetic wave is emitted and scattered through the ground. A UHF RFID tag attached to a front surface location region of assets receives electromagnetic waves of various paths emitted by the tag reader. The tag reader reads UHF RFID tag information. A transfer function of a tag receiving signal is constructed according to the tag information, and a path loss function during a UHF RFID tag sensing electromagnetic wave process is constructed according to the transfer function. The path loss is calculated according to the constructed path loss function. A location of the UHF RFID tag is obtained.

A control system for an industrial vehicle includes a badge communicator and an information linking device. The badge communicator has a transceiver for short range communication with electronic badges that are within a fixed short range of the badge communicator, defining a first zone.
