Remote Scanner for Secure Mobile POS Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile transaction systems require users to relinquish their devices to strangers for payment processing, compromising security and convenience, especially when sensitive information is involved.
Innovation Solution
A remote scanner system that communicates with a POS terminal to request and receive transaction information from a mobile device, allowing secure and convenient transactions without physically handing over the device, using wireless communication technologies like NFC, Bluetooth, or WiFi, and incorporating security features such as restrictions and self-destruct mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user hands their mobile device to a waiter or valet for transaction processing, then the transaction can be completed, but the user loses control over their device and sensitive information
Solution Approach 1:
A remote scanner acts as an intermediary device between the user's mobile device and the POS terminal. The scanner communicates with the mobile device wirelessly to retrieve transaction information without requiring physical handover, while maintaining security through restricted data access and monitoring mechanisms
2Ease of operation
If a user relinquishes their mobile device to a stranger for payment processing, then the transaction can be completed, but the user becomes unable to communicate with friends, family, and emergency service providers
Solution Approach 1:
The remote scanner serves as a mediator that enables transaction processing without requiring the user to relinquish control of their mobile device, thereby maintaining communication capabilities with contacts and emergency services while completing the payment transaction
3Reliability
If the POS terminal is located in an inaccessible area, then the terminal can be securely positioned, but the user cannot easily access it for transactions
Solution Approach 1:
The transaction system is segmented into multiple components: the POS terminal remains securely positioned in the backend, while a remote scanner is deployed to the user's location. This segmentation allows the terminal to maintain security while the scanner provides user accessibility for transaction initiation and information retrieval
Data Source
AI summary
Devices, systems, and methods are disclosed which relate to using a remote scanner for mobile transactions. A point of sale (POS) terminal communicates with a remote scanner that is removably coupled to the POS terminal. Logic on the POS terminal generates a request for a transaction information and transmits the request along with a restriction to the remote scanner. Logic on the remote scanner receives the request and the restriction, transmits the request to a mobile device, receives the transaction information while monitoring the restriction, and transmits the transaction information to the POS terminal for processing. The transaction information may be provided subject to the restriction.
