Automated Banking Machine Privacy Shield and Light Emitter
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 being accessible for visually impaired users or those with disabilities.
Innovation Solution
The automated banking machine incorporates a user interface with a concealed keypad, encrypted input capabilities, a touch screen display, and features such as louvers for secure input viewing, a light emitter to prevent camera surveillance, and a design that includes a large display and auxiliary touch screen for easier operation by users with disabilities, along with improved weather sealing and germ reduction measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard keypad is used for user input, then the machine is simple to manufacture, but security is compromised as users can be observed entering their inputs
Solution Approach 1:
A privacy shield or partition is introduced as an intermediary element between the keypad and the external environment. This shield blocks the line of sight to the keypad, preventing observation of user inputs while allowing the keypad to remain functional. The intermediary structure resolves the contradiction by adding security without fundamentally changing the keypad's core functionality.
2Reliability
If a concealed keypad with privacy features is implemented, then security and privacy are improved, but the device complexity increases
Solution Approach 1:
The privacy shield is merged with the existing keypad housing or surrounding structure of the ATM. By integrating the privacy feature into the existing device architecture rather than adding it as a separate component, the complexity increase is minimized while still achieving the security benefit of preventing observation of user inputs.
3Adaptability or versatility
If a standard display size is used, then the device is compact, but accessibility for visually impaired users and those with disabilities is reduced
Solution Approach 1:
The display system incorporates dynamic scaling capabilities that allow the display elements to be enlarged or adjusted in size based on user needs. This dynamic adjustment feature enables the display to adapt to visually impaired users by providing larger text and icons, while maintaining the physical compactness of the device when standard display sizes are sufficient.
4Object-affected harmful factors
If traditional ATM components are used, then the machine is simple to operate, but it lacks features to prevent germ transmission
Solution Approach 1:
High-contact components such as physical keypads and buttons are extracted or replaced with contactless alternatives like touchless sensors, optical scanners, or voice recognition systems. This extraction of contact points eliminates the primary vectors for germ transmission while maintaining the core functionality of user input, thereby reducing harmful factors without significantly increasing device complexity.
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
The solution provides enhanced security, improved user accessibility, and operational ease for diverse users, while ensuring secure transactions and reducing germ transmission, all while maintaining weather resistance.
Implementation Method 1
At least one light emitter is associated with the at least one input device. The emitter is operative to emit light at an intensity that is sufficient to cause a camera directed at the input device to not be able to effectively view the input device
Data Source
AI summary
An apparatus that operates to cause financial transfers responsive to data read from data bearing records, includes at least one processor that is in operative connection with a card reader, a check acceptor, a cash dispenser and a display. The at least one processor causes the machine to operate to read card data from a user card, and to cause a determination to be made that the read card data corresponds to an authorized financial account. The at least one processor is operative to cause data to be read from a check and/or cash to be dispensed, and a financial transfer to or from the account corresponding to the value thereof. Machine instructions are output and user transaction inputs can be received through either a primary or an auxiliary touch screen display.
