There is provided a system that uses a two-dimensional information code. The system administers an information code which is provided with a data recording region and an image region. The system is provided with a specific information acquisition section that acquires specific information of a subject or an object, as information recorded in the data recording region, or as information to be correlated to the information recorded in the data recording region. Further, the is provided with a unique image acquisition section that acquires a unique image of a subject or an object, or a unique image for specifying the subject or the object, as information indicated in the image region. Further, the system is provided with a registration section that registers specific information acquired by the specific information acquisition section, being correlated to a unique image acquired by the unique image acquisition section.

The invention consists of dimensional interlocking blocks with computer readable labeling and also human readable labeling on each side. The labeling consists of computer instructions or of sets or lists of instructions. When connected together the computer code is built, and is readable as a system by humans and by computers.

A detection apparatus (10) is provided having a plurality of optoelectronic sensors (20) that are arranged in different positions and orientations to record respective image information of different sides of an object (14) and having an evaluation unit (22) to process the image information. In this respect, the evaluation unit (22) is configured to recognize views of a respective side of the object (14) in the image information and to arrange the views in a plane such that the original arrangement on the object (14) can be restored.

A retail store is comprised of a retail space having billboard paper with images of items and item codes for purchasing the items. The retail store further includes a pick area where physical items of the store are located. A device operated by a user scans the item codes and the item codes are communicated to a server for item information and item pricing. As item identifiers are moved to a cart depicted on the device by the user, the server communicates the item details to a display device in the pick area where corresponding items are picked for a transaction of the user in real time. When the user checks out and pays for the items in the cart, the user retrieves the bagged items for the transaction from a pickup drive-thru accessible from an external area of the retail store where the pick area is located.

In some examples, deterring a third party from copying a product or process may include scanning code to generate scanned code. Text in the scanned code may be read and/or at least one image in the scanned code may be recognized. The text and/or the at least one image may be analyzed to determine whether the code includes a specified trademark. Based on a determination that the code includes the specified trademark, an indication of authenticity of the code may be generated.

A method of identifying data items by wave blocks, each wave block comprising a set of unique features distinguishable from the unique features of other wave blocks. The unique features of the wave blocks are extracted and stored. A plurality of wave tags are defined, each comprising a set wave blocks. A mapping of the set of wave blocks to each wave tag is stored. A request for a wave tag to identify a data item is received and a wave tag is assigned to the data item. The wave tag is broadcasted and is captured by a capturing device, which extracts the unique features of the wave blocks. The wave tag is identified by comparing the extracted features of the wave blocks with the stored features of the plurality of wave blocks. The data item is identified from the mapping of the data item to the wave tag.

A computer can comprise a housing, a microprocessor disposed within the housing, a display, and a communication interface communicatively coupled to the microprocessor. The computer can be configured, responsive to locating decodable indicia within content viewable on the display, to decode the decodable indicia to produce at least one decoded message. The computer can be further configured to display the content with decoded message data being embedded into the content. The decoded message data can be provided by at least one decoded message, data derived from the decoded message.

A method for locating an optical code, on the basis of a finder pattern of the optical code, in an image having a plurality of pixels, the method comprising the steps of determining at least one candidate position for the finder pattern on the basis of edge transitions along at least one line through the image; determining a final position of the finder pattern in a vicinity of the candidate position; and verifying the final position, i.e. verifying that the image comprises the finder pattern in the final position, using a known property of the finder pattern.

A control device having a surface that is hidden after installation of the control device. The control device includes an optical code disposed on the surface. The optical code encodes a device identifier of the control device and a secret code. The control device includes a wireless transceiver configured to communicate with a user device during a provisioning sequence of events that is initiated based on the user device scanning the optical code to obtain the device identifier and the secret code.
