Removable Battery Module with Encryption for Secure Payment Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable user interface terminals require frequent upgrades due to evolving hacking threats and digital financial fraud schemes, leading to high replacement and operating costs, as they need to be physically modified or replaced entirely to incorporate new secure card readers, NFC transceivers, and improved encryption.
Innovation Solution
A removable rechargeable battery module with integrated power management, communication, and encryption circuitry, including wireless transceivers and secure storage, which can be easily upgraded or replaced, allowing for software updates and security patches to be downloaded during recharging, thereby reducing the need for full device replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portable user interface terminals are frequently upgraded to add newly developed secure card readers, NFC transceivers, and improved encryption, then information security and protection against hacking threats are improved, but device replacement and modification costs increase significantly
Solution Approach 1:
The patent divides the portable terminal into modular components, specifically separating the battery module (containing power management and communication circuitry) from the main terminal body. This segmentation allows the battery module to be independently upgraded or replaced without replacing the entire terminal, thereby reducing upgrade costs while maintaining security improvements.
Solution Approach 2:
The patent extracts the communication and encryption circuitry into a separate, removable battery module that can be independently managed. This extraction enables businesses to upgrade security features by replacing only the battery module rather than the entire terminal device, directly addressing the cost issue while maintaining improved encryption and security capabilities.
2Adaptability or versatility
If portable user interface terminals are replaced or physically modified to incorporate new secure card readers and NFC transceivers, then adaptability to new payment technologies is improved, but operating and maintenance costs increase
Solution Approach 1:
By segmenting the terminal into a main body and a separate battery module containing communication and payment interfaces, the system enables independent upgrading of the battery module to support new payment technologies without replacing the entire terminal, thus improving adaptability while reducing operating costs.
Solution Approach 2:
The battery module is designed as a universal component that can be removed and replaced to support different payment technologies and security standards over time. This multi-functionality approach allows a single terminal body to adapt to various payment systems through battery module replacement, reducing the need for multiple specialized devices and lowering overall operating costs.
3Reliability
If entire portable user interface terminals are replaced to maintain security against evolving fraud schemes, then protection against digital financial fraud is improved, but financial investment and replacement costs increase
Solution Approach 1:
The patent segments the terminal into a permanent main body and a replaceable battery module containing security-critical components. This allows businesses to maintain fraud protection by periodically replacing the battery module with updated versions, rather than replacing the entire terminal, thereby reducing financial investment while maintaining security.
Solution Approach 2:
The patent enables a cycle where the battery module can be discarded (removed from service) and recovered (replaced with an updated module) to maintain security without discarding the entire terminal investment. This approach allows businesses to recover the value of the main terminal body while only investing in the necessary security updates through battery module replacement.
