Education curricula materials include encoded indicia such as a QR code that contains information related to identifying requested augmented reality image data from a server over a network. By scanning the QR code, a computer uses its decoding software to create a data set for transmitting to the server. The data set may include an identifier for selected augmented reality image data associated with the user's curriculum, information about the curriculum at issue, the academic level of the user, and any other data necessary to ensure that the most appropriate augmented reality image data is transmitted back to the computer. The server transmits comprehensive augmented reality image data back to the computer for viewing on a computerized display accessible by a student. Part of the content may include an interactive pedagogical agent that helps the student with a part of the instruction related to a portion of the curriculum.

Vehicles in traffic are expected to communicate wirelessly, to avoid collisions and facilitate the flow of traffic. Unfortunately, in 5G and 6G, the process of finding a wireless address of a specific vehicle is slow and difficult. Disclosed is a “connectivity matrix”, an emblem that vehicles can display, showing a pattern of black and white squares that forms a unique code. Another vehicle can autonomously read the code and look up the wireless address in a tabulation. The tabulation relates each code to the relevant wireless address, and optionally other information about the vehicle. The two vehicles can then transfer messages, including emergency messages, without delay. At freeway speeds, this can save lives. A central entity maintains the tabulation, ensuring that each wireless address is associated with a unique connectivity matrix code. Roadside companies and access points can also display a connectivity matrix, promote communication with prospective customers.

Disclosed are a two-dimensional code based communication method, a two-dimensional code based communication apparatus, and a two-dimensional code based lift desk, wherein the communication method comprises: acquiring, by a controller, address information of a communication module, and transmitting the address information, together with product information, to a displaying module; generating, by the displaying module, a two-dimensional code based on the address information and the product information, and displaying, by the displaying module, the two-dimensional code; and scanning, by a smart terminal, the displayed two-dimensional code to establish communication with the communication module. The present disclosure may achieve the following effects: upon connecting with the communication module via the smart terminal, it becomes unnecessary to search all surrounding communication modules and then select one to connect; instead, the present disclosure ensures an accurate connection by directly scanning the two-dimensional code, which prevents misconnection and facilitates the user to use; besides, the two-dimensional code is displayed via the displaying module, which avoids aging or loss of the two-dimensional code.

A two-dimensional code processing method and a device. The method includes: obtaining, by a first electronic device, two-dimensional code information displayed by a second electronic device; obtaining first scenario information, where the first scenario information is scenario information related to the first electronic device; determining two-dimensional code data and second scenario information based on the two-dimensional code information, where the second scenario information is scenario information related to the second electronic device ; and when determining that the first scenario information and the second scenario information meet a preset condition, performing, by the first electronic device, preset processing on the two-dimensional code data. The scenario information of the two electronic devices that need to perform two-dimensional code interaction is compared, and further, two-dimensional code verification is completed.

This application discloses method, an apparatus, a storage medium, and an electronic device for bar code generation and display. The method includes: obtaining a target code by compiling a source code, the target code being self-contained executable code comprising target computer readable instructions and comprising logic functions, wherein the target computer readable instructions are executable by a processor; and generating a target bar code embedded with the target code by encoding the target code, wherein the target code comprises at least one of the following logical functions: a first logical function for allowing a scanning device with a read permission to run the target code, a second logical function for allowing the target code to be run within a validity period, and a third logical function for calling and configuring target hardware in the scanning device to execute a target operation.

A method may include generating, by a computing device, a first dynamic QR code comprising a plurality of QR code frames, each QR code frame transmitted at a first frequency, the plurality of QR code frames comprising non-viable QR code frame(s) and at least one viable QR code frame. The method may include displaying, by the computing device, the first dynamic QR code, the at least one viable QR code frame displayed at a first time. The method may include transmitting, by the computing device, a first pulse to a user device. The method may include capturing, by the user device at the first time and in response to receiving the first pulse, the at least one viable QR code frame. The method may include generating and displaying, by the user device, a second dynamic QR code, causing the computing device to complete a requested transaction.

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.

Image processing apparatuses and information processing systems are disclosed. In one example, user information is generated on condition that a session is being established with a provision destination of a captured image, and the user information is provided to an information processing device that stores imaging location information. Alternatively, acquisition of imaging location information is permitted on the basis of permission information obtained from a provision destination on the condition that a session is being established with the provision destination of a captured image, the imaging location information provided from the information processing device associated with an imaging location is acquired in the permitted state, and the imaging location information and the user information are provided to an external device that verifies the user information.

A device (12, 312, 494) operates to cause financial transfers responsive to data read from data bearing records. The device includes a reader (20, 314) that is usable to read check data from financial checks. The reader is also usable to read record document data such as an invoice or other remittance advice. At least one circuit (54, 332) of the device is operative to cause a determination to be made that check data and/or record document data corresponds to stored data. Responsive to the determination, check data and record data are made available to a payee terminal (346). The device may be operable responsive to receipt of embedded instructions from a check payment website to capture image data corresponding to an image of a financial check and to send the image data to a remote computer as indicated by the embedded instructions.

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.
