ATM Keypad Cover and Encryption for Secure Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated banking machines lack enhanced security, user-friendly operation, weather resistance, and features to prevent germ transmission and unauthorized viewing of user inputs, while also not effectively utilizing currency bills with tracking devices.
Innovation Solution
The development of an automated teller machine (ATM) with a user interface that includes a concealed keypad, encryption capabilities, a secure touch screen display module, and features to minimize germ transmission, along with the ability to operate with currency bills that include tracking devices, and enhanced security measures to prevent unauthorized access and data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard keypad is provided for user input, then ease of operation is improved, but security against unauthorized viewing and germ transmission deteriorates
Solution Approach 1:
A flexible keypad cover made of material such as vinyl or plastic is provided that can be placed over the keypad. The cover acts as a physical barrier that prevents unauthorized viewing of key presses and reduces germ transmission by creating a protective layer between users and the shared keypad surface.
Solution Approach 2:
The keypad cover serves as an intermediary element between the user's fingers and the keypad. It mediates the interaction by allowing users to press keys through the cover while maintaining security and hygiene benefits, thus resolving the contradiction between ease of operation and protection against harmful factors.
2Reliability
If currency bills with tracking devices are used, then security and traceability are improved, but device complexity and handling requirements worsen
Solution Approach 1:
The patent replaces mechanical handling and tracking methods with electronic tracking devices embedded in currency bills. These devices use electronic signals and data communication to provide security and traceability, eliminating the need for complex mechanical tracking systems while improving reliability.
Solution Approach 2:
The tracking devices embedded in currency bills serve multiple functions including security verification, transaction tracking, and authentication. This multi-functionality reduces the need for separate security mechanisms and simplifies the overall system while improving reliability.
Data Source
AI summary
A card actuated automated banking machine (10) is operative to carry out financial transactions responsive to data included on user cards. The banking machine includes a user interface (15) including a display (24). The user interface includes a card reader (16) which is operative to read data on user cards which identify at least one of user and a user's financial accounts. A fascia of the machine includes a keypad (404, 438, 458) through which users input confidential data. Covers (400, 422, 430) prevent unauthorized persons from viewing confidential inputs to the keypad. Authorization signals assure that the display is operating in a manner that provides appropriate user instructions. A visual indicator is operative to indicate to a user that keypad inputs are being encrypted. Alternatively a touch screen display module (608) is operative to securely receive manual inputs and/or card data.
