An electronic guest book assembly for tracking attendees of an event includes a host electronic device, such as a tablet computer. Host programming code positioned on a computer processor of the host electronic device enables a display of the host electronic device to present to a host a list of attendees of an event, such as a funeral. The host programming code also enables the host electronic device to store the list of attendees on an internal storage unit of the host electronic device. Attendee programming code, which is selectively positionable on a microprocessor of an attendee electronic device, such as a smart phone, enables the attendee electronic device to receive and to selectively display information and images related to the event. The attendee programming code also enables the attendee electronic device to signal the host electronic device of an arrival of an attendee associated with the attendee electronic device.

A secure cryptocurrency transactional system for actuating transactions involving electronic gaming machines and cryptocurrency wallets.

Disclosed herein are methods and systems for encoding data in composite patterns such that the encoded data is perceptible in one or more infrared spectral ranges while significantly imperceptible in visible light spectral range by encoding the data in one or more first partial patterns and/or in one or more second partial patterns of the composite pattern where the first partial pattern(s) is painted using a first print material and the second partial pattern(s) is painted using a second. The first and second paint materials are characterized by reflecting substantially similar light in the visible light spectral range and significantly different light in the infrared spectral range(s) such that the first and second patterns are indistinguishable in the visible light spectral range while highly distinguishable in the infrared spectral range(s). further disclosed are methods and systems for decoding the composite patterns to decode and extract the encoded data.

An electronic device is disclosed. The electronic device includes a memory, a camera module, a communications module, and a processor that is configured to: receive, from the camera module, image data associated with a machine-readable optical label, the optical label encoding transaction details of a transfer of data to a recipient account, wherein the transaction details do not indicate an identity of the recipient account; receive a user input indicating authorization to initiate a transfer of data, via a protected resource, from an account associated with the user to the recipient account; and in response to receiving the user input, generate a request for initiating the transfer of data based on the transaction details, the request including an access token for use in authenticating the user on requests to access the protected resource.

A system includes: a processor; a memory coupled to the processor, wherein the memory stores a first content; a medical device coupled to the processor; and a reader coupled to the processor, wherein the reader is configured to read a second content from a storage medium other than the memory such that the processor switches the medical device from a first mode to a second mode based on the first content corresponding to the second content.

Computer program products, methods, systems, apparatus, and computing entities are provided for an augmented reality display using an actual image of the item. Additionally, the present disclosure provides for a proportionally dimensioned representation of the item in the augmented reality display. In some aspects, a beacon/tag/sensor-based approach may be used. In some aspects, a marker-based approach may be used.

This disclosure relates to a data storage device. A data port transmits data between a host computer system and the data storage device over a data channel. The device repeatedly broadcasts advertising packets over a wireless communication channel different from the data channel. Each advertising packet comprises a random value and a message authentication code calculated based on the random value and an identity key. The identity key is readable by a device to be connected and in proximity of the data storage device out of band of the data channel and the communication channel. The identity key enables the device to be connected to verify the message authentication code based on the random value and the identity key to thereby authenticate the data storage device.

Disclosed are systems, methods, and non-transitory computer readable media for making virtual colored markings on objects. Instructions may include receiving an indication of an object; receiving from an image sensor an image of a hand of an individual holding a physical marking implement; detecting in the image a color associated with the marking implement; receiving from the image sensor image data indicative of movement of a tip of the marking implement and locations of the tip; determining from the image data when the locations of the tip correspond to locations on the object; and generating, in the detected color, virtual markings on the object at the corresponding locations.

The present disclosure relates to a portable production machine, a mobile terminal, a production system having a portable production machine and a mobile terminal, and a method for capturing data. According to aspects of the disclosure, on the production machine - which can be, for example, a welding machine or cutting machine - production data is automatically captured, organized into data sets, and converted into data set images, which are displayed on a display device. The displayed data set images are captured with a mobile terminal and transmitted to a central server. As a result, a plurality of production machines can be incorporated into a data system without the need for any changes to the hardware in the production machines.

Method for providing a container with food, the method comprising: providing a container for infant formula food, adding the food, sealing the container with a gas-tight membrane seal, adding an inner scannable code on the gas-tight membrane seal, closing the container with a tamper-proof closure means, so that the inner scannable code is not scannable without breaking a part of the tamper-proof closure means, and storing the inner scannable code in a database.
