According to one embodiment, there is provided an image forming device that prevents write information from being incorrectly written to a non-target RFID tag. The image forming device according to the embodiment includes: a placement unit, a wireless tag communication unit, and a conductor. A sheet provided with a wireless tag can be placed in the placement unit. The wireless tag communication unit can write information to the wireless tag provided on the sheet. The conductor is provided in the placement unit and hinders communication between the wireless tag communication unit and the wireless tag.

Various embodiments illustrated herein disclose a radio-frequency identification (RFID) reader having a first RFID tag having a first antenna element operating at a first transmit power. The first RFID tag receives, in a first time interval, a first interrogation command from a first RFID reader through the first antenna element. The first RFID tag transmits, in the first time interval, a first response signal to the first RFID reader. The RFID reader comprises a second antenna element that operates at a second transmit power and a processor communicatively coupled to the second antenna element. The processor transmits, in the first time interval, a second interrogation command to one or more second RFID tags through the second antenna element. The first RFID tag transmits, in a second time interval, a third interrogation command to a first RFID tag of a second RFID reader through the first antenna element.

In order to process a mobile transaction offline, a user terminal transmits a mobile transaction code and a merchant terminal ID to a payment information transmission server and the payment information transmission server transmits a payment information message including the mobile transaction code to a merchant terminal, so that it is possible to process mobile transactions through a unified user interface despite different payment plans of various payment service providers.

A smart container for facilitating operations in a facility is provided. The smart container includes an apparatus configured to store and transport one or more items, one or more electronic devices disposed one or more sides on the apparatus, and a wheel-based charging system coupled to the apparatus and configured to charge one or more battery packs for the one or more electronic devices. The one or more electronic devices are configured to transmit information for monitoring and tracking a position of the smart container throughout an environment.

The present disclosure relates to a method to check if a connector system with a Connector Position Assurance (“CPA”) member is in a closed position. The method includes providing an RFID-tag reader that is positioned at a distance D to the integrated circuit enabling far-field RFID communication and not permitting near-field RFID communication. Further, the method includes checking the readability of the integrated circuit with the RFID-tag reader and issuing an alert signal if the integrated circuit is not readable by the RFID-tag reader indicating that the CPA member is not in the closed position.

Systems and methods of the invention relate to managing an inventory of items within a storage container. A storage container can house one or more items for distribution among one or more users such as, for instance, employees. The storage container discussed herein provides authentication of a user, tracking of the inventory each user removes or returns, video/image capture of user during access of the storage container, wireless tracking of items housed within the storage container, among others. The storage container can provide flame retardant protection and/or electrical isolation to one or more items located within the storage container.

A method for estimating channel parameters includes: sending a paging signal for identifying the tag device; sending training sequence information, receiving first training sequence feedback information during a non-working period of the tag device, receiving, during a working period of the tag device, second training sequence feedback information modulated by the tag device, and estimating the channel parameters of the tag device according to the training sequence feedback information and the second training sequence feedback information. The tag device having at least one antenna of the present disclosure can modulate carrier signals to transmit information, has advantages such as a fast transmission rate, a large amount of transmission data and a strong anti-interference capability, and can adapt to different application scenarios.

A store having an automated checkout can automatically associate multiple shoppers with a single purchase. For example, a mother and her children can walk independently through the store and select items. Upon checkout, the items selected by the mother and children can all be charged to the mother's credit card in a single purchase. The system and method discussed herein can capture images of multiple shoppers from one or more video streams of a store area, can associate the multiple shoppers with one another from the captured images when the multiple shoppers appear together in a check-in area of the store, can track the movement of the multiple shoppers within the store from the captured images, can track items selected by the multiple shoppers from the captured images, and can initiate a transaction that charges the selected items to an account associated with one of the multiple shoppers.

In accordance with a first aspect of the present disclosure, a channel equalizer is provided for use in a near field communication (NFC) device, the channel equalizer comprising: a filter configured to receive an input signal and to generate a filtered output signal; an estimator configured to determine filter coefficients to be used by said filter; a synchronizer configured to determine when to enable the channel equalizer and to provide one or more corresponding control signals to the estimator. In accordance with a second aspect of the present disclosure, a corresponding method of operating a channel equalizer for use in a near field communication (NFC) device is conceived.

Methods and devices for determining movement associated with an antenna of a receiver are disclosed herein. An example method includes generating a first acceleration signal associated with the antenna, wherein the first acceleration signal includes one or more substantially non-zero axial components. The method may further include establishing an acceleration signature corresponding to the antenna based on the first acceleration signal, and generating a second acceleration signal associated with the antenna, wherein the second acceleration signal includes one or more substantially non-zero axial components. The method may further include determining a signal difference between the acceleration signature and the second acceleration signal, wherein the signal difference is attributable to a movement of the antenna. The method may further include generating an alert signal indicating the movement.
