Wearable Device Transaction Management via Verified Host Session
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to access and manage their accounts or perform transactions using mobile devices that are not readily accessible, such as when the device is in a pocket or bag, making it difficult to respond to notifications or initiate functions like phone calls or payments.
Innovation Solution
A wearable electronic device that can be wirelessly paired with a host device, allowing users to access and manage accounts, initiate functions, and perform transactions by establishing a verified communication session, using NFC for communication with POS terminals, and storing account information for secure and convenient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users carry mobile devices everywhere for account management and transactions, then accessibility to account functions is improved, but convenience deteriorates when the device is not readily accessible (in pocket or bag)
Solution Approach 1:
The patent segments the mobile device functionality into two parts: a host device that stores account information and a wearable device that provides access to that information. The wearable device contains a processor, memory, and display, while the host device contains the payment account information and communication modules. This segmentation allows the wearable device to be readily accessible on the user's wrist while the host device can be stored away.
Solution Approach 2:
The wearable device acts as an intermediary between the user and the host device's account information. It establishes a verified communication session with the host device and retrieves account information through this intermediary channel, allowing users to access account functions without directly handling the host device.
2Speed
If mobile devices are kept accessible for quick transactions, then response time is improved, but security deteriorates due to potential unauthorized access
Solution Approach 1:
The patent segments account information storage from access functionality. The host device securely stores payment account information while the wearable device provides the access interface. This segmentation allows fast transactions through the wearable device while maintaining security through controlled information retrieval via verified communication sessions.
Solution Approach 2:
The system implements feedback mechanisms through verified communication sessions between the wearable and host devices. The host device verifies the wearable device's identity before providing account information, and the wearable device confirms successful retrieval. This feedback loop ensures secure access while maintaining speed.
3Productivity
If account information is stored in the wearable device for quick access, then transaction speed is improved, but device complexity increases
Solution Approach 1:
The patent extracts the heavy burden of storing sensitive account information from the wearable device and places it in the host device. The wearable device only stores minimal access credentials and retrieves full account information through verified communication sessions when needed. This extraction maintains transaction speed while reducing wearable device complexity and security risks.
4Reliability
If verified communication sessions are established between wearable and host devices, then security is improved, but communication overhead increases
Solution Approach 1:
The patent implements preliminary action by establishing verified communication sessions in advance before transactions occur. The wearable and host devices perform verification and establish secure channels beforehand, so that when a transaction is needed, the communication is already authorized and ready to proceed quickly without repeated verification delays.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to conveniently manage accounts and perform transactions without needing to access the host device directly, providing secure and efficient access to various functionalities and account management, even when the host device is not readily accessible.
Implementation Method 1
The wearable device can establish communication with the POS terminal, e.g., using a near-field communication ('NFC') transceiver.
Data Source
AI summary
A wireless device can store account identifiers and facilitate transactions. The wireless device can be loaded with user account identifiers and can be presented to various checkpoint devices. When presented, the wireless device can transmit a selected account identifier to the checkpoint device. In the context of a purchase transaction, the checkpoint device can be a point-of-sale terminal and the account data can be financial account data. In some instances, the wireless device can also facilitate a purchase transaction, e.g., by obtaining information about products to be purchased, constructing a purchase order from the product information, and transmitting the purchase order to a point-of-sale terminal.
