Smart Glass Dynamic NFT Touchless Transaction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional approaches to electronic transactions at ATMs and merchant devices lack efficiency and security, particularly in scenarios where physical contact needs to be minimized, such as during public health threats or emergencies.
Innovation Solution
A smart glass-based system utilizing dynamic non-fungible tokens (NFTs) that captures geographical coordinates and user biometrics, combined with a distributed ledger system, enables secure and touchless transactions by generating a valid NFT for authentication, allowing users to interact with ATMs and merchant devices without physical contact through eye movements and eye blinks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional contact-based transaction interfaces are used, then device compatibility and ease of operation are maintained, but security and hygiene are compromised due to physical contact requirements
Solution Approach 1:
The patent replaces mechanical contact-based interaction (buttons, screens, card insertions) with optical detection systems (eye-tracking cameras, facial recognition sensors). Users interact through eye movements and facial expressions without physical contact, eliminating mechanical interaction points while maintaining operational capability.
Solution Approach 2:
The patent introduces an intermediary authentication layer using biometric verification (facial recognition, iris scanning) between the user and the transaction system. This intermediary validates user identity and intent without requiring direct physical contact with transaction devices, bridging security requirements with user convenience.
2Object-affected harmful factors
If physical contact interfaces are used for transactions, then device simplicity is maintained, but exposure to contaminants and security risks increases
Solution Approach 1:
The patent eliminates mechanical contact points by substituting them with optical and sensor-based detection systems. Cameras capture eye movements and facial features, while sensors detect proximity and authentication data, completely removing the need for physical interaction surfaces that could harbor contaminants.
Solution Approach 2:
The patent creates digital copies of user biometric data (facial structure, iris patterns, eye movement characteristics) to authenticate transactions. These digital replicas serve as contactless identifiers, replacing physical cards, keys, or direct contact authentication methods that could transmit contaminants.
3Reliability
If contactless authentication methods are implemented, then hygiene and security are improved, but authentication time and processing complexity increase
Solution Approach 1:
The patent performs preliminary biometric data collection and authentication verification in the background before the actual transaction is initiated. User facial features and biometric data are captured and validated in advance, so that when a transaction is needed, authentication has already been completed or is ready for rapid verification.
Solution Approach 2:
The patent maintains continuous authentication readiness by keeping biometric verification systems actively monitoring and prepared. The eye-tracking and facial recognition systems remain engaged throughout the interaction, allowing seamless transition from authentication to transaction execution without interruption or repeated verification steps.

AI summary
A wearable computing device, such as a smart glass device, may be used to facilitate touchless and/or frictionless transactions at computing devices in the vicinity of the wearable computing device based on a dynamic non-fungible token (NFT). The smart glass device captures biometric information of a user, such as an iris image, and generates the NFT based on the biometric information, a geographic location and a time. The NFT is authenticated via a blockchain by an authentication system at a remote network. Upon validation, the smart glass device presents user interface screens to initiate the transaction. A computing device receives a request message to complete the transaction based on the NFT.
