Solution Overview
Problem
Self-service terminals, such as ATMs, face challenges in maintaining secure data transmission without direct electrical or radio connections, which are vulnerable to data attacks and infiltration, especially in sensitive applications where direct telecommunications connections are undesirable.
Innovation Solution
Implementing a currentless and radio-free data transmission method using optical or acoustic signals, where data is converted into barcodes or acoustic signals for local display and recording, then transmitted via conventional telecommunications, utilizing electro-optical converters and acoustic couplers to avoid electrical and radio links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct telecommunications connections are used for data transmission, then data transfer efficiency is improved, but security against data attacks and virus infiltration deteriorates
Solution Approach 1:
The patent introduces an optical interface as an intermediary medium between the self-service terminal and external communication devices. Data is converted to optical signals (barcodes, QR codes, or direct optical transmission) which are then captured by external devices. This intermediary optical layer prevents direct electrical connection, thereby blocking virus infiltration and data attacks while maintaining efficient data transfer capability.
Solution Approach 2:
The patent replaces the traditional electrical/mechanical connection system with an optical system. Instead of using electrical cables or direct radio frequency connections that are vulnerable to hacking, the system uses optical signals (light-based communication) for data transmission. This substitution eliminates the electrical connection vulnerability while preserving data transfer functionality.
2Object-affected harmful factors
If optical or acoustic signal transmission is used, then security against data attacks is improved, but device complexity increases
Solution Approach 1:
The patent designs the optical interface to serve multiple functions within a single integrated system. The same optical interface can display barcodes/QR codes for data transmission, function as a visual display for user information, and potentially serve as an input device. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity despite the enhanced security features.
3Object-affected harmful factors
If conventional telecommunications connections are avoided, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent enables the self-service terminal to autonomously generate and display optical data signals (barcodes, QR codes) without requiring complex manual intervention. The terminal itself performs the data conversion and presentation, making the security-enhanced interface as easy to operate as traditional methods. Maintenance personnel simply need to capture the displayed optical code, a straightforward task that does not require specialized knowledge.

Data Source
AI summary
In order to maintain self-service terminals (SS terminals), data must be transferred to a data center by means of telecommunication connections. However, in particularly sensitive fields of application, a direct link of SS terminals to external networks or devices is undesirable. Usually, the maintenance personnel must then access the service and diagnostic data locally at the SS terminal and share said data with the help desk personnel in the data center by telephone. In order to be able to transfer the maintenance and diagnostic data directly between the SS terminal and the data center even without directly linking the SS terminal, the data are transferred in a current-free and radio-free data transfer form in the vicinity of the self-service terminal (100) by means of sending and receiving devices (150, 160, 170; MA, CAM, F). This can occur, e.g., by displaying and reading in barcodes (BCs).
