Innovation Solution
A method and system where a point of sale system receives contactless payment data from a mobile device via a contactless payment terminal and communicates a token to the mobile device, configured to initiate particular communication functionalities, including WiFi access, content presentation, and digital key operations, using near field communication (NFC) links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contactless payment data is received from a mobile device, then payment transaction capability is improved, but the ability to initiate additional communication functionalities (WiFi, content presentation) deteriorates without network infrastructure
Solution Approach 1:
The patent uses NFC as an intermediary communication channel to transfer tokens from the contactless payment terminal to the mobile device. This intermediary mechanism enables the mobile device to receive authentication tokens and initiate WiFi or content presentation functionalities without requiring direct connection to the payment terminal's network infrastructure, thus resolving the contradiction between functionality initiation capability and network dependency.
2Ease of operation
If tokens are communicated to mobile devices via contactless payment terminals, then user experience is improved through seamless connectivity, but transaction processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring tokens with the necessary authentication data and communication parameters before the actual transaction completion. The token is prepared in advance with embedded WiFi credentials or content presentation parameters, allowing the mobile device to immediately initiate the desired functionality without requiring additional authentication steps or network configuration during the transaction, thus improving ease of operation while minimizing time loss.
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 seamless and secure initiation of communication functionalities on mobile devices, such as WiFi access and content presentation, without the need for network infrastructure, enhancing user experience and transaction efficiency.
Implementation Method 1
NFC is a is a set of communication protocols that enable two electronic devices, one of which usually is a mobile device (e.g., a smartphone, tablet computer, etc.), to establish communication by bringing the devices within a threshold distance (e.g., 4 cm) of one another
Data Source
AI summary
Contactless payment data can be received from a mobile device via a contactless payment terminal. Responsive to receiving the contactless payment data from the mobile device, a token can be communicated to the mobile device via the contactless payment terminal, the token configured to be processed by the mobile device to initiate a particular communication functionality by the mobile device.
