A face recognition-based method includes, when a terminal detects a placement posture on the terminal, obtaining placement posture information of the terminal, where the placement posture information is used to determine a tilt angle of the terminal relative to a first plane; performing facial recognition on a user when determining that a tilt angle meets a preset range without notifying the user and regardless of detecting an action of the terminal other than obtaining the placement posture information; and opening the application when the facial recognition succeeds.

Provided is an information management system that comprises: a payment information confirmation device which is connected over a network to a cryptocurrency system management terminal that manages a cryptocurrency system, which extracts transaction information including address information for a seller account in a cryptocurrency system, and which generates and transmits payment confirmation information including at least a transfer amount from the extracted transaction information; and a register device which is connected to the payment information confirmation device, receives the payment confirmation information from the payment information confirmation device, displays the received payment confirmation information, converts the currency units of an entered transaction amount into a cryptocurrency units payment amount in the currency units of the cryptocurrency system, generates a two-dimensional code in which are recorded the cryptocurrency units payment amount and the address information, and displays the generated two-dimensional code.

The various implementations described herein include methods, systems, and devices for Augmented Reality (AR) based messaging. In one aspect, a method includes processing a user request to create and place an avatar (e.g., a virtual representation of a user) at a user-specified location. In another aspect, a system manages placement of avatars at various geo locations, allows users to interact with avatars, and manages avatar-avatar interactions with or without user controls. In yet another aspect, a device is provided allowing a user to create, manage, and view avatar-based tags. Additionally, various user interfaces are provided to support the user to create, manage, and view avatars.

A networked computer system for storing promotional awards associated with non-fungible tokens (NFTs) is described herein. The networked computer system includes a master engagement record blockchain system including a plurality of master engagement records associated with NFTs, an engagement computer server system, and a plurality of kiosk terminals. A kiosk processor is programmed to capture a dynamic NFT verification (DNV) displayed on a user's mobile device via a kiosk camera and display the plurality of engagement activities via the display touchscreen. The processor of the engagement computer server system performs algorithm steps including determining a promotional award associated with the user selected engagement activity upon receiving the engagement activity completion message from the kiosk processor, and recording a master engagement record to the master engagement record blockchain system associating the determined promotional award with the user owned NFT.

A server system of an embodiment for transaction processing includes a virtual point-of-sale server to register data of a customer transaction based on data received from a first terminal operated by the customer in a selling area and a management server. The management server generates a machine-readable code including information for acquiring the transaction data and an electronic settlement method. The management server transmits the machine-readable code to the first terminal upon receiving a checkout instruction. Upon receiving information for acquiring the transaction data from a second terminal, the management server acquires the transaction data from the virtual point-of-sale server, and processes an electronic payment if the information regarding the electronic settlement method is received from the second terminal.

A system and method for pay-to-print printing allows a pay-to-print user to pay from any source currency to target currency through the use of a cryptocurrency service. A user selects a job to be performed on an MFP, and a job cost is generated and displayed. The MFP generates and displays a barcode on its touchscreen. The user scans the barcode and their smartphone is directed to a payment service portal, such as Google Pay or Apple Pay. The user directs payment to a crypto currency sever, along with payment target and target currency for the job. The cryptocurrency server converts payment to its cryptocurrency, and then to the target currency, and relays the target currency to target. The MFP completes the job once payment has been made.

In one embodiment, a method includes receiving, by a payment server and from a messaging application executing on a first mobile device operated by a first user, a request to initiate a payment transaction using a payment application. The request includes a payment amount and an identifier associated with the first user. The method includes facilitating a first adjustment to a balance associated with the financial account of the first user in the data store identified based on the identifier. The method includes generating a link associated with the first adjustment and transmitting the link to the first mobile device. The method includes, upon receiving from a second user operating a messaging application, an indication that the second user has interacted with the link within the messaging application, facilitating a second adjustment of a balance of a financial account of the second user according to the payment amount.

Systems and methods for securely generating and printing documents are disclosed. For example, processor(s) of a computer system may receive information for the document from a computing device through a network, verify the information for the document, and upon verification, generate document generation data using at least a portion of the information for the document. The document generation data may include document metadata that enables generation of an image of the document and/or the image of the document. Upon the processor(s) verifying first authentication information of a first code associated with a printing device received from the computing device through the network and second authentication information of a second code associated with the computing device received from the printing device through the network, the processor(s) may transmit the document generation data to the printing device through the network, and cause the printing device to print the image of the document.

Systems and methods for securely pairing a transmitting device with a receiving device are described. The systems and methods may communicate with a first device via a first communication method over a wireless communication network. The systems and methods may transmit, to the first device via a second communication method, a first sensory pattern representing a first key. In addition, the system and methods may communicate with the first device via the first communication method using the first key.

A security authentication system for a website provides a safe login without having to directly enter an ID and a password on a user device requesting login to the website. A first user device receives one-time use authentication information from a second user device after the second user device received the one-time use authentication information from an authentication server without the authentication server receiving user login authentication information from the second user device. A request is transmitted to the authentication server based on the one-time use authentication information and the user login authentication information. In response to the request, one-time password (OTP) information is received from the authentication server. The OTP information is presented by the first user device, such that the OTP information can be entered into the second user device and used in a request to log in to the website.
