According to embodiments, a device includes a camera configured to read a symbol attached to a commodity and capture an image containing discount information attached to the commodity; a commodity information storage configured to store information regarding the commodity acquired by reading the symbol attached to the commodity; a first evaluator configured to determine whether prior commodity information stored in the commodity information storage includes information related to invisible information, in response to reading discount information attached to the commodity; a second evaluator configured to determine whether commodity identification information included in the discount information is identical to commodity identification information included in the information related to the invisible information, in response to the first evaluator determining that the prior commodity information stored in the commodity storage includes the information related to the invisible information; and an output generator configured to output information related to the discount information.

A secure indicator includes a substrate, a barcode symbol that has a plurality of barcode modules provided on the substrate, and a security material positioned proximate the barcode symbol on the substrate. The security material is configured to be activated by irradiation at one or more predetermined activation wavelengths. Additionally, the barcode symbol is configured to be read (i) before the security material is activated and (ii) while the security material is activated.

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.

In some implementations, a locationing system may receive, from a user device, locationing information associated with the user device. The locationing information may include signal-based locationing information associated with a wireless communication device associated with the locationing system and an object identifier associated with an object identified by read data obtained by a reader of the user device. The locationing system may determine, based on the object identifier, object location information associated with the object. The locationing system may determine, based on the signal-based locationing information, device location information associated with the user device. The locationing system may determine, based on the object location information and the device location information, a location of the user device. The locationing system may perform an action associated with the location and the user device.

A setting system comprises a first electronic device and a second electronic device. The first electronic device is configured to output information for the second electronic device. The second electronic device is configured to acquire the output information from the first electronic device and change a setting of the second electronic device on the basis of the output information. The first electronic device is further configured to automatically erase the information from a memory of the first electronic device after confirming that the second electronic device has acquired the information from the first electronic device.

Described are embodiments that are useful for generating procedures for entering data prior to separating liquid into liquid components. The embodiments are applicable to procedures for entering data prior to separating blood into components. Graphical elements are displayed that allow a user to appreciate the workflow of someone who implements the procedures. As a result, the user can create a procedure that is simple, efficient, and is less prone to errors.

Disclosed is a substrate with a marking thereon. A part of the substrate has a two-dimensional structure attached thereto, and a part of the marking is present on the structure and the other part of the marking is present on the substrate itself.

A pairing management method includes detecting, by a computer, a peripheral device configured to perform short-range wireless communication with the computer; transmitting, by the computer, to a server storing pairing information generated by a pairing process of a management terminal and the peripheral device, an acquisition request for the pairing information of the detected peripheral device; and performing data communication, by the computer, with the detected peripheral device, based on the pairing information, when the pairing information associated with the transmitted acquisition request is received from the server.

A setting system comprises a first electronic device and a second electronic device. The first electronic device is configured to output a password and setting information for the second electronic device. The second electronic device is configured to acquire the password and the setting information from the first electronic device, change setting of the second electronic device on the basis of the setting information, and lock the setting of the second electronic device using the password.

A navigation system for an automated guided vehicle comprises a set of marking elements which are to be arranged in grid form on the floor and in which navigation information is encoded; a sensor device to be arranged at the automated guided vehicle for reading navigation data from the marking elements; and an evaluation device connected to the sensor device for generating control signals for the automated guided vehicle with reference to read navigation data. Each of the marking elements has at least two graphical code patterns that are each designed as one-dimensional code patterns and comprise a code applied along a scanning direction, with the scanning directions of the at least two graphical code patterns being aligned offset from one another by an angular offset.
