A greeting card having a scannable code with a unique identifier representative of a unique location on a computer network with the unique location having a first response with a first set of data. The scannable code can be scanned, a first time, to display a first response having a first set of data. The first response can be replaced by a second response having a second set of data.

A system and method for controlling recall of a product in a computer network. A pair of product keys can be assigned to the product including a private product key and a public product key. A pair of product recall keys can be assigned to a product recall, including a private product recall key and a public product recall key. A data processing device assigned to a manufacturer in the computer network can be configured to print a matrix code on the product and generate a recall transaction assigned to the product indicating a recall request for the product. The data processing device can sign the recall transaction with the private product recall key and a private manufacturer key. A second data processing device is configured to scan the printed matrix code on the product and provide the public product recall key by decrypting the printed matrix code.

A method for authenticating an object, particularly a security element for protecting value documents, ID documents and products, as well as a security element, a security document, a reader, an individualization device and a server for such a method. The method involves the steps: dividing a first code element into at least one first partial code element and one second partial code element, storing the second partial code element, arranging the first partial code element and/or a second code element on and/or in the object, jointly machine-capturing the first partial code element and the second code element by means of a reader, extracting the first partial code element and the second code element from the data captured by the reader, accessing the stored second partial code element using the second code element as a key, checking whether the code element resulting from merging the extracted first partial code element and the stored second partial code element corresponds to the first code element.

A system, method, and computer program product for implementing electronically generated promotion deployment is provided. The method includes receiving electronic data comprising shipment identification for a shipment of an item from a shipping client to a recipient. A profile is generated for the recipient and a further client associated with a freight carrier is authorized to generate visible promotional structures associated with packages for delivery by the freight carrier. Promotional attributes from the further client are cross referenced with respect to a package comprising the item for the recipient. The cross referencing may include matching demographic profiles, of recipients of pending delivery packages, to additional profiles selected by a promotional entity for each pending delivery package. A visible promotional structure associated with the promotional attributes is generated and presented during delivery of the package. The visible promotional structure may include a physical structure or a digital structure.

An example non-transitory computer-readable medium includes instructions to generate a linear pattern of contrasting elements. The linear pattern encodes scannable information. The instructions are further to generate shifted instances of the linear pattern, a shifted instance being shifted with respect to the linear pattern along a length of the linear pattern. The instructions are further to form an array of the shifted instances of the linear pattern orthogonal to the length of the linear pattern to generate a two-dimensional pattern of the contrasting elements. The two-dimensional pattern repeatedly encodes the scannable information.

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 portable label printer for printing content onto a surface of a label is provided. The label has a chip disposed therein. The portable label printer includes a main body, an RFID antenna assembly, a front cover unit, a back cover unit, and a print head module. The front and back cover units are disposed in the main body, and a paper exit port is formed between the front and back cover units. The RFID antenna assembly is disposed in the main body and adjacent to the paper exit port. The print head module is disposed in the main body and under the RFID antenna assembly. The label first passes through the print head module, and then passes through the RFID antenna assembly. When the label passes through the RFID antenna assembly, the RFID antenna assembly performs data reading or data writing on the chip of the label.

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.

The disclosure discloses a tape printer including a data receiving portion, a display control portion, and a print control portion. The data receiving portion is configured to receive talk data containing plural pieces of speech related data along a time series, the speech related data including speech display texts from each of a first and a second speaker. The display control portion is configured to control the display device so that the plural pieces of speech related data is arrayed and displayed in order of the time series along a tape length direction, and first and second speech related data respectively in relation to the first and second speaker contained in the talk data are displayed in mutually different forms. The print control portion is configured to control a printing head to form a plurality of print objects corresponding respectively to the plural pieces of speech related data.

It is an object of the present invention to improve visibility for observation with naked eyes or for camera shooting without spoiling the appearance during marking inside a. transparent medium using a laser. By irradiating an inside of a transparent medium with a laser, the present invention forms a micro-denatured region in each of a first layer and a second layer inside the medium. The micro-denatured regions in the respective layers are arranged out of alignment with each other on a two-dimensional plane (refer to FIG. 1).
