According to the present disclosure, a mobile terminal comprises: a display unit; a sensing unit configured to sense a code scanning situation indicating the situation in which a code scanner scans a code; and a controller configured to control the display unit to automatically display a code for a first payment task when the code scanning situation is sensed and adjust a direction in which the code is displayed according to a direction of light outputted from the code scanner.

A method and system for cold chain monitoring of perishable goods includes at least one environmental sensor (102) to monitor at least one environmental parameter, a controller (104) to log a plurality of readings from each of the at least one environmental sensors (102), and a machine readable display (114) to display at least one alarm status associated with the plurality of readings via a barcode.

A computing system can receive, over the one or more networks, a request for a service from a client device of a user. In response to receiving the request, the system can generate a unique identifier for the request to facilitate a rendezvous between the user and a service provider, and transmit the unique identifier to the client device of the user. Based on the user and the service provider making the rendezvous, the system receives data corresponding to the unique identifier from a provider application executing on a client device of the service provider. Based on receiving the data corresponding to the unique identifier from the client device of the service provider, the system updates a status for the user to indicate that the service has been provided by the service provider for the user.

Application integration for contactless payments is described. In an example, a payment making platform can provide a transaction code to a payment processing platform. The transaction code can be presented at a point-of-sale of a transaction between a customer and a merchant associated with the payment processing platform. Upon detecting an interaction between the transaction code and a computing device of the customer, the payment making platform and the payment processing platform can exchange data to enable the customer to participate in the transaction via the computing device of the customer. In some examples, the payment making platform and the payment processing platform can process a contactless payment for the transaction by transferring funds associated with an account of the customer from the payment making platform to the payment processing platform for depositing into an account of the merchant.

A wireless, Bluetooth® paired connection is established between a wireless, electro-optical reader and a host by reading a multi-parameter, pairing symbol displayed by the host. An identification parameter is extracted from the pairing symbol to automatically identify the host, and one or more configuration parameters are substantially simultaneously extracted from the same pairing symbol to automatically configure the paired connection between the reader and the host.

Embodiments are described in which information from multiple devices is merged through the exchange of linking information. For example, a two dimensional barcode is used associate information originating from different devices. In embodiments, information is associated with various levels of trust based on a variety of factors to quantify whether or not and to what extent collected information can be relied upon to be accurate. In embodiments, information from multiple sources is merged into a common transaction record that can be accessed through use of the linking information so the information can be efficiently retrieved even though it originated, or was captured, by different devices.

Vehicles in traffic cannot coordinate their actions properly in 5G and 6G without knowing the location and the wireless address of the other vehicle. GNSS signals are generally too slow and too imprecise to discern vehicles in, for example, adjacent lanes. Directional wireless beams are subject to reflections from conducting surfaces, producing chaotic signals and false locations if more than one vehicle is within the transmission beam. To provide precise localization in traffic, methods are disclosed for multiple vehicles (or other mobile devices) to acquire satellite signals simultaneously, and then analyze the data differentially, thereby canceling major uncertainties (such as propagation variations, ephemeris motion, and clock jitter), and thereby determining the relative positions precisely. Unlike prior-art “precision” positioning methods, the disclosed methods do not require averaging multiple acquisitions. On the contrary, examples show how high differential precision can be obtained without averaging, using measurements acquired at the predetermined time.

Disclosed are a method and device for recognizing a two-dimensional bar code for improving the efficiency of recognizing the two-dimensional bar code. The method comprises: a relative position of a household appliance and a terminal device is determined during network configuration of the household appliance; a display parameter for displaying the two-dimensional bar code is determined according to the relative position, wherein the display parameter comprises a size of the two-dimensional bar code to be displayed and the two-dimensional bar code carries device information of the household appliance; the display parameter is sent to the household appliance to enable the household appliance to display a two-dimensional bar code picture according to the display parameter; and the two-dimensional bar code picture is recognized to obtain the device information of the household appliance.

An image processing apparatus including a display unit includes a processor and a memory storing instructions, when executed by the processor, causing the image processing apparatus to function as a detection unit that detects occurrence of a sheet jammed inside the image processing apparatus and a display control unit that displays a screen based on detection of the occurrence of the jammed sheet. The screen includes a first region for displaying work that a user carries out to remove jammed sheets from inside the image processing apparatus and a second region for displaying work that the user carries out after removing the jammed sheets from inside the image processing apparatus.

A mobile bar code scanning device with a pinch-to-window feature includes an embedded camera and a user interface system having a visual display. The user interface system enables the user to access features of the mobile barcode scanning device with touch gestures. The mobile barcode scanning device also includes a barcode scanning application initialized by a user of the mobile barcode scanning device. The mobile barcode scanning device also includes an operating system communicatively coupled to the embedded camera, the barcode scanning application, and the user interface system. The visual display provides a viewfinder for the embedded camera in the barcode scanning application. The user-defined pinch-to-window feature is real-time adjustable in size, orientation, and position by at least a two-point touch gesture.
