A multi-function transaction card may include a card body having dimensions that are in accordance with a standard for transaction cards, an output device on the card body, and a secure element within the card body. The multi-function transaction card may pair, via a wireless connection, the multi-function transaction card with a terminal. The multi-function transaction card may receive, from the terminal, information associated with a transaction. The multi-function transaction card may generate, based on the information associated with the transaction, and using a cryptographic key, an authorization request cryptogram (ARQC), wherein the cryptographic key is stored in the secure element. The multi-function transaction card may generate, based on the ARQC, a machine-readable code. The multi-function transaction card may display, using the output device, the machine-readable code.

The disclosure provides an approach for measuring performance between a virtualized desktop infrastructure (VDI) client running on a client device and a remote computing device. Embodiments include generating, by a performance client on the client device, an event and storing a time associated with generating the event. Embodiments include transmitting, by the VDI client to the remote computing device, a message based on the OS event. Embodiments include determining, by a performance agent on the remote computing device, a time associated with receiving the message at the remote computing device and causing an indication of the time to be displayed in a virtual desktop screen. Embodiments include extracting, by the performance client, from the virtual desktop screen, the time, and determining a performance metric based on the extracted time and the time associated with receiving the message at the remote computing device.

A reduced size optical code identifier includes a transparent body having a flat bottom surface with a rounded or domed top surface that meets the bottom surface around the perimeter of the bottom surface. An optical code is provided in the body adjacent the bottom surface and is visible through the top surface. The top surface is configured to reduce reflection to facilitate optical recognition and decoding of the optical code. The body has a maximum length or diameter of about twelve millimeters or less. The identifier can be placed on an object or structure and then used to associate information with the optical code of the identifier so that the information can be retrieved using a computing device that can optically recognize the code and communicate with a remote server.

Image data depicting a 2D machine-readable code is up-sampled and compressed with a lossy compression process before being sent from a client device to a remote server for code reading. The remote server decompresses the sent information, extracts a payload from the machine-readable code, and causes result information to be sent back to the client device for display or other action. The up-sampling and compression operations performed on the client device can employ software instructions that are downloaded to, and executed by, browser software on the client device. Many other features and arrangements are also detailed.

Various embodiments of a physical instrument are described herein. The physical instrument comprises a reference array platform having a top surface and a bottom surface. A reference array including one or more different fiducial markers is disposed on the top surface of the reference array platform. The reference array platform may have a bent physical configuration or a tilted physical configuration. An adhesive layer is disposed on the bottom surface of the reference array platform.

The Tag Element System allows users to create, upload, and share virtual content in the physical world utilizing the Tag Element System platform, “Enhanced Tag Elements”, and a smart device such as a smartphone or tablet. Any user can record a video or create other content and attach it to an Enhanced Tag Element simply by scanning or otherwise interacting with it with their smart device. The system provides a user interface to enable a user to create and upload new content upload previously stored content to the Tag Element System. Once content is uploaded, the user can share the Enhanced Tag Element with another user to allow that user to access, modify, and/or interact with the content.

A device configured to identify a first digital document in a digital document repository, to identify a first graphical code that represents the first digital document, and to send the first graphical code to an approved user device. The device is further configured to obtain a second graphical code that represents a public encryption key for the organization and to extract the public encryption key for an organization from the second graphical code. The device is further configured to obtain a third graphical code from the approved user device. The third graphical code represents a second digital document comprising data and a digital signature that was signed using a private encryption key for the organization. The device is further configured to determine the third graphical code passes validation using the public encryption key for the organization and to store the second digital document in a digital document repository.

An adhesive-backed label having a plurality of adhesive-backed label portions, each of the adhesive-backed label portions comprising an instance of an identifying indicia, whereby one or more of the plurality of adhesive-backed label portions is applied to at least one collected sample so that the identifying indicia on the adhesive-backed label portion on the collected sample corresponds to the identifying indicia on at least one of the adhesive-backed label portions that remains on the adhesive-backed label, at least one of the adhesive-backed label portions on the adhesive-backed label also comprising a field configured to receive additional identifying indicia.

A computer program product includes a non-volatile computer readable medium and non-transitory program instructions embodied therein, the program instructions being configured to be executable by a processor to cause the processor to perform various operations. The operations may include obtaining first encoded data that encodes information of a first party, obtaining second encoded data that encodes information of a second party, performing a forward mashup algorithm on the first encoded data and second encoded data to form a third data set, and providing the third data set to the first party as a mashup two-dimensional barcode.

A system for verifying a user operating an Automated Teller Machine (ATM) sends an authentication media item to a user device associated with the user when the ATM receives a transaction request. The system receives, from the ATM, a first image of the authentication media item when the authentication media item is presented to the ATM. The system compares the first image of the authentication media item with a second image of the authentication media item stored in a user profile associated with the user. The system extracts a first unique code from the first image of the authentication media item, and a second unique code from the second image of the authentication media item. The system determines whether the first unique code corresponds to the second unique code. The system approves the transaction request if it is determined that the first unique code corresponds to the second unique code.
