Embodiments disclosed herein describe a multi-dimensional code storage and transfer system. The system gets electrical power from the flash light of a typical smart device, and displays a time-varying multi-dimensional code which can be captured and decoded by the smart device. The system can be made by printed electronics technology.

An electronic tag device for cargo or baggage comprising a housing, a microcontroller, a memory, a wireless communications module, and a sensor module. The microcontroller is configured to receive itinerary data via the wireless communications module while the microcontroller is operating in a first mode and store the itinerary data in memory. The itinerary data may include at least a place of departure, a departure time, a place of arrival, and an arrival time. The microcontroller is further configured to enter a second mode based on at least one of the departure time in the itinerary and sensor data received from the sensor module, wherein the wireless communications module is disabled in the second mode, and return to the first mode based on at least one of the arrival time in the itinerary and sensor data received from the sensor module. The microcontroller will communicate with a remote system using the communications module while in the first mode and turn off all communication while in the second mode.

This disclosure is generally directed to an RFID system that includes a hybrid RFID tag offering a functionality of a passive RFID tag and an active RFID tag. When operating as a passive RFID tag, an RF signal received from an RFID reader is harvested to produce a DC voltage for powering the hybrid RFID tag. The harvested DC voltage is coupled into a capacitor at a slow-charging rate so as to avoid a capacitor inrush current causing an abrupt power supply voltage drop. A controller chip in the hybrid RFID tag can execute some RFID functions at this time, thereby speeding up a response to the RFID reader. The capacitor is then charged at a fast-charging rate for storing a reserve charge. The hybrid RFID tag can subsequently use the reserve charge to operate as an active RFID tag without waiting for an RF signal from the RFID reader.

A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Gift cards may be inputted by a user into such a payment card or other device such that a user can combine gift cards. Similarly, a user be provided with a global payment account that can be utilized in multiple countries that have different standards for formatting data. A user may be provided with a default country (e.g., United States) but may have a way to select that the user is in a different country (e.g., Japan). Accordingly, a user may select that a Japanese data structure be transmitted through a magnetic stripe reader when the user is in Japan.

In accordance with various embodiments, a radio communication processor arrangement including a chip and a battery integrated into the chip is provided.

Provided is a smart card that can prevent malfunction in the smart card and improve stability of radio frequency communication by removing interference of an AC signal generated at the antenna terminal of the smart card. The smart card includes: a dual antenna configured of a first antenna and a second antenna for performing radio frequency communication with a card reader; an IC chip electrically connected to the first antenna to perform radio frequency communication through the first antenna; a power generation unit for generating DC power by converting a radio frequency signal received through the second antenna; a control unit for receiving the DC power generated from the power generation unit to control various modules; and a cut-off unit arranged between the first antenna and the IC chip to cut off a radio frequency signal received through the first antenna under the control of the control unit.

A wireless tag reader includes a casing, an antenna in the casing and through which a radio wave is transmitted to and received from a wireless tag on an article, a control device in the casing and configured to read tag information stored in the wireless tag based on a radio wave received by the antenna, and an elastic member between the casing and the antenna so as to permit the antenna to be movable with respect to the casing.

A power source, charging system, and inductive receiver for mobile devices. A pad or similar base unit comprises a primary, which creates a magnetic field by applying an alternating current to a winding, coil, or any type of current carrying wire. A receiver comprises a means for receiving the energy from the alternating magnetic field and transferring it to a mobile or other device. The receiver can also comprise electronic components or logic to set the voltage and current to the appropriate levels required by the mobile device, or to communicate information or data to and from the pad. The system may also incorporate efficiency measures that improve the efficiency of power transfer between the charger and receiver.

A livestock management system for detecting, tracking, and responding to livestock location and physical parameters, and for determining livestock behavior and physical conditions correlated thereto. The system generally includes a plurality of tags and sensors attached to and implanted in a plurality of livestock, one or more local sensors, a management platform, and a remote computer system. Each tag receives, processes and maintains data regarding the location, activity and physical parameters of a livestock to which it is attached and locally determines the behavior and physical conditions of the livestock. The tags communicate with other nearby tags and sensors locally via dynamic mesh networks and with the management platform and remote computer system via longer range wireless networks. The management platform processes the tag data and produces herd-related data. The remote computer uses the tag data to generate and update livestock behavior and condition models for download to the tags.

An RFID tag includes a circuit board and a plurality of functional modules. The circuit board has an antenna conductor and a ground plane. On the circuit board, a control circuit and an RFID IC are mounted. The functional modules are connected to the circuit board. The circuit board includes a main part and an extended part. The main part includes a mounting plane for the control circuit and the ground plane. The extended part includes the antenna conductor and is integrated with the main part. The extended part and the antenna conductor are longer than one edge of the main part and disposed along the one edge.
