Self-Service Terminal Using Portable Device Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ATMs are costly due to expensive user interface elements like displays and keypads, limiting their deployment by financial institutions.
Innovation Solution
A self-service terminal system that uses a communication port and dispense area, allowing users to operate with their own portable communication devices, such as PDAs or cellular telephones, eliminating the need for a display and keypad, and utilizing a network connection for transaction authorization and media dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional user interface elements (display, keypad) are included in the ATM, then the user interface functionality is complete and user-friendly, but the cost of the ATM becomes relatively high
Solution Approach 1:
The patent extracts the user interface elements (display, keypad) from the ATM itself and relocates them to the user's portable communication device. The ATM retains only the essential dispensing functionality, while the user's mobile device provides the interface for interaction. This separation dramatically reduces ATM cost and complexity while maintaining full user interface functionality through the user's own device.
Solution Approach 2:
The patent introduces a communication port as an intermediary between the ATM and the user's portable device. This intermediary enables data transmission and interaction without requiring expensive display and keypad components in the ATM. The communication port serves as a minimal interface that leverages the user's existing device capabilities.
2Ease of operation
If the ATM includes expensive user interface elements, then the user can interact with the terminal conveniently, but the number of ATMs that a financial institution is willing to deploy is reduced
Solution Approach 1:
By extracting the expensive user interface elements from the ATM and placing them in the user's portable device, the patent dramatically reduces per-ATM cost. This cost reduction enables financial institutions to deploy significantly more ATMs, increasing overall service availability and productivity while users retain full interaction capability through their own devices.
Solution Approach 2:
The patent leverages the universality of portable communication devices that users already possess. Instead of requiring each user to interact with a dedicated ATM interface, the system works with any standard portable device, making the ATM infrastructure more scalable and deployable without sacrificing user interaction quality.
3Device complexity
If the user interface consists of a communication port and dispense area only, then the cost and complexity of the ATM is reduced, but the user must provide their own user interface device
Solution Approach 1:
The patent achieves adaptability by designing the ATM to work with universal portable communication devices that users already own. The communication port interface is designed to be compatible with multiple device types, allowing the simplified ATM structure to adapt to various user devices without requiring device-specific customization.
Solution Approach 2:
The patent effectively copies the user interface functionality from the ATM to the user's portable device. Instead of building interfaces into the ATM, the system leverages the existing interface capabilities of the user's device, copying only the essential transaction data and commands through the communication port.

AI summary
A self-service terminal (14 or 114 or 214) and a system (10, 100, 200) including a plurality of networked self-service terminals are described. Each terminal (14, 114, 214) has a simple user interface. In one type of terminal (114 or 214), the user interface consists of a dispense area. In another type of terminal (14), the user interface consists of a dispense area (40) and a communication port (38). In one of the systems (10) a user is able to execute a transaction using a portable communication device (24 or 26) implementing a local wireless technology. In the other systems (100 or 200) a user is able to execute a transaction using a cellular network.
