NFC Mobile Payment Tokenization via Multi-Channel Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile wireless communication devices are limited in their ability to facilitate transactions across various platforms due to their reliance on specific communication channels, such as NFC, which are not universally available, and have limited functionality in transactions.
Innovation Solution
A system and method that utilizes a hand-held mobile device with both a secure element and a radio element, allowing for communication between these elements via different channels (NFC, Bluetooth, or WIFI) to facilitate transactions by sending transaction requests and responses through a management server and transaction server, enabling compatibility with multiple point-of-sale terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC communication channel is used for mobile transactions, then transaction security and simplicity are improved, but platform compatibility and universal usability deteriorate
Solution Approach 1:
The mobile device is equipped with multiple communication transceivers (NFC, Bluetooth, Wi-Fi) that can function across different transaction platforms. The system selects appropriate communication channels based on the transaction environment, enabling universal usability while maintaining security through tokenization regardless of the specific communication channel used.
Solution Approach 2:
A server acts as an intermediary between the mobile device and point-of-sale terminals. The server receives transaction requests, generates tokens, and manages the tokenization process, allowing the mobile device to communicate securely through various channels without exposing sensitive card information, thus maintaining security while improving platform compatibility.
2Adaptability or versatility
If multiple communication channels are supported in mobile devices, then platform compatibility and usability are improved, but device complexity increases
Solution Approach 1:
The system includes automatic channel selection and token management capabilities that operate without user intervention. The mobile device and server automatically determine the appropriate communication channel and handle token generation/validation, reducing the perceived complexity for users while maintaining multi-channel support.
Solution Approach 2:
The server acts as a central coordinator that manages the complexity of multiple communication channels. It receives requests from the mobile device, determines the appropriate communication protocol, and handles the tokenization process, thereby offloading complexity from the mobile device while maintaining platform compatibility.
3Reliability
If tokenization is implemented in mobile transactions, then transaction security is improved, but system complexity and processing overhead increase
Solution Approach 1:
The server serves as an intermediary that handles the complex tokenization process. It receives transaction requests, generates secure tokens, and manages token validation, thereby centralizing the security-critical functions and reducing the complexity burden on the mobile device while maintaining high transaction security.
Solution Approach 2:
Instead of storing and processing sensitive card information directly on the mobile device, the system creates and uses token copies that represent the card data. These tokens are generated and managed by the server, simplifying the mobile device's security requirements while maintaining transaction security through the use of equivalent token representations.

AI summary
The present invention provides a method and apparatus for completing a transaction using a wireless mobile communication channel and another communication channel, particularly another communication channel that provides for near field radio channels (NFC), as well as other communication channels, such as Bluetooth or WIFI. The present invention also provides a method of completing a transaction in which a management server assists a transaction server and a point of sale terminal in forwarding transaction information to a hand-held mobile device, with the transaction having originated from the hand-held mobile device. There is also provided a hand-held mobile device that wirelessly communicates between a secure element and a radio element that are associated with the hand-held mobile device.
