Secure Element for Mobile Transaction Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless mobile devices are limited in their ability to perform transactions across various platforms, as they are often tied to specific communication protocols and lack versatility in transaction capabilities, particularly with near field communication (NFC) devices only being usable with NFC readers.
Innovation Solution
A method and system that configures a mobile communication device to perform transactions using a second communication channel distinct from its primary voice data channel, by attaching a secure element with a processor, memory, and wireless transceiver to enable transaction data transmission through a separate channel to a remote terminal, allowing for broader transaction compatibility and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC devices are used for transactions, then secure simple transactions are enabled, but the devices are limited to working only with NFC readers and lack platform versatility
Solution Approach 1:
The patent implements a secure element that can operate across multiple communication protocols and platforms. The secure element is designed to work not only with NFC readers but also with other communication channels including Bluetooth, Wi-Fi, and cellular networks, enabling a single device to perform secure transactions universally across different platforms and terminals.
Solution Approach 2:
The secure element acts as an intermediary component that bridges different communication protocols and platforms. It translates and manages secure transactions across various communication channels, allowing the mobile device to interact with different types of terminals (NFC readers, Bluetooth devices, Wi-Fi terminals) through a unified secure interface.
2Device complexity
If a single communication channel is used for voice and data, then device simplicity is maintained, but transaction capability and flexibility are limited
Solution Approach 1:
The patent segments the communication functionality by introducing a separate secure element with its own wireless transceiver for transaction data, distinct from the primary voice and data communication channel. This segmentation allows the device to maintain simplicity in its main communication path while adding specialized transaction capability through the secure element's dedicated communication channel.

AI summary
A method for configuring a mobile communication device to perform transactions using a second communication channel that is different from a first communication channel through which the mobile communication device sends voice data. The method includes attaching a secure element to the mobile communication device. The secure element includes a memory storing an application, a processor configured to execute the application stored in the memory; and a wireless transceiver configured to send transaction data associated with the executed application through the second communication channel to a terminal that is remote from the mobile communication device.
