A system and method of providing two-way communication between an isolated POS system and a website are described. The POS system operates as an air gap system. In response to detecting a trigger event the two-way communication is initiated for installation, diagnostic and repair services. POS information for transmission to the website through the internet is generated using a QR code that includes the website address and a data payload that depends on the desired service. The QR code is read by a smart phone and transmitted to the website. The website responds by sending response data dependent on the QR code and desired service. The response data is communicated to the POS system via another QR code for further operations by the POS system based thereon.

Method and systems described herein may provide multifactor mutual authentication. A first server may provide a first party and a second party with at least two authentication components in order for the first party to authenticate the identity of the second party, and vice versa. The first authentication component may include a color-based authentication component, while the second authentication component may include a code-based authentication component. Both factors need to be validated in order for the authentication to be successful. The color-based authentication component, in combination with the code-based authentication component, may improve the speed with which the mutual authentication is performed.

A means for food allergy management system, a smart AI driven restaurant menus on QR Code or barcode for enhanced dining experience is disclosed. This software invention brings Artificial Intelligence to restaurant menus, making them smarter, intelligent, enhanced and multilingual with advanced dish and item visuals and descriptions, strong analytics and hyperlinks to the meaning of industry terms. By bringing exceptional skills for content intelligence and ingredient safety management to menus, this invention fills the void on previously restaurant menus.

The present invention relates to a method and apparatus to determine the position of an image sensor relative to a predetermined continuous pattern of colors and/or objects based on the images said patterns of colors and/or objects produces within the image sensor.

A pack of lottery tickets includes a plurality of inter-connected lottery tickets fan-folded into a stack, wherein each lottery ticket comprises a first side edge. A code on each lottery ticket identifies the pack and an order or position of the lottery ticket in the pack. A marking pattern is printed along the first side edge of each of the lottery tickets and includes at least one mark. The pack has a side face defined by the stacked first side edges of the tickets in the stack, wherein the marking pattern on the lottery ticket side edges align so as to form a unique identification image on the side face of the pack. The marking pattern on each lottery ticket is unique to the respective ticket such that each lottery ticket in the pack can be separately authenticated at a later time by comparing its marking pattern to a retrieved or replicated image of the marking pattern based on the pack identification and order of the lottery ticket in the pack provided by the ticket code.

The disclosure relates to a package for an assay kit, comprising an insert that provides for convenient, e.g. one step, scanning of reagent and other assay kit information from assay kit reagent containers that are disposed within the insert. The disclosure also describes methods of preparing such an insert and of assembling the assay kit.

An aerosol generating apparatus is provided. The apparatus comprises a chamber configured to receive an article comprising an aerosolizable medium, a sensor arrangement configured to detect a first marker arrangement on the article and a second marker arrangement on the article. The second marker arrangement is located at a predetermined position relative to the first marker arrangement. The apparatus further comprises a controller, configured to determine a plurality of comparison values by comparing a plurality of first marker regions in the first marker arrangement with the second marker arrangement, and determine data associated with the article based on the plurality of comparison values.

There is provided a print apparatus and a media roll for the print apparatus, comprising a media identifier located on an end of a core section of the media roll. A type of media loaded into the print apparatus is determined by sensing the media identifier on the media roll using a non-contact sensor to scan the end of the core section.
