A representative simulation of the over-65 target audience by Minds shows that 72% of older Sparkassen customers experience significant cognitive load during app navigation. Validated against official data from the Statistisches Bundesamt, this study highlights that unclear icons and complex two-factor authorization severely limit digital accessibility in retail banking.

Digital Banking Adoption Barriers for Older Demographics in Germany
In Germany, according to current data from the digital association Bitkom, around 74% of people over 65 are active online. The Statistisches Bundesamt also confirms a continuously increasing level of digital activity in the 65-plus age group in its surveys on internet use. Nevertheless, there is a significant gap between general internet use and the secure, independent use of mobile banking apps. Many Sparkassen and regional banks face the challenge of digitally engaging this growing, yet often hesitant target group without overwhelming them with complex user interfaces.
However, traditional market research methods like physical focus groups or lab-based UX testing hit strict limits with this age group. Recruiting older participants for on-site sessions is time-consuming, expensive, and often unrepresentative, as it primarily attracts tech-savvy seniors while the critical mass of hesitant users remains underrepresented. This is where Minds' Target Audience Simulation offers a highly efficient alternative. By anchoring real demographic and psychographic data models, cognitive profiles and accessibility requirements can be precisely simulated. This is achieved in less than an hour, completely bypassing the logistical effort and high costs of traditional panels.
The results of the Minds simulation show that the cognitive load of using the Sparkassen app increases exponentially with age. A central friction point is menu navigation. While younger generations are accustomed to intuitive, icon-based navigation, older users require clear, text-based labels and consistent paths. Frequent app updates that alter visual elements or menu structures lead to immediate disorientation for seniors.
Constant updates keep changing the menu navigation. I often spend minutes searching for the simple transfer function because the icons are not clear to me.
The simulation shows that icons considered standard by UX designers are often misunderstood by older users. For example, the three-line icon, also known as the hamburger menu, is not recognized as a main menu by many participants over 65. Placing key features like photo transfers in nested submenus also drastically increases abandonment rates. Instead of simplifying things, visual overload leads to a fear of making mistakes. Because older users have an extremely low tolerance for errors in financial matters, they prefer to abandon the process and visit a physical branch, which in turn increases service costs for the Sparkassen.
A critical bottleneck in the customer journey of older Sparkassen customers is the transaction authorization process. The separation between the primary banking app and the authorization app, such as push-TAN, represents an insurmountable hurdle for many seniors. The forced switching between two applications requires a high level of working memory and technical understanding.

When I have to open the push-TAN app to authorize a payment, I lose track of what I was doing. Switching back and forth between two apps causes me pure stress.
The Minds simulation clearly quantifies this problem: 64% of simulated interactions in the over-65 age group fail during two-factor authentication. Participants lose context when switching apps, forget previously entered data, or fail due to session timeouts. Many older users do not perceive this process as an added security benefit, but rather as a technical hurdle. The fear of triggering an incorrect transfer or locking their account with a wrong click is omnipresent. As a result, they avoid digital channels for active transactions and use expensive paper-based transfers instead.
Alongside cognitive load, physical limitations play a decisive role in app usage among older demographics. Declining eyesight and limited fine motor skills make operating small smartphone screens difficult. The Minds simulation integrates these physical profiles to analyze the visual ergonomics of the Sparkassen app in detail.

The font sizes are far too small in some submenus, even at the maximum system setting. I am afraid of overlooking a zero and sending the wrong amount.
The results show that insufficient contrast and touch targets that are too small represent the most common physical barriers. Even if the font size is increased in the smartphone's operating system, many elements within the Sparkassen app do not adapt dynamically. This leads to cut-off text or overlapping buttons. Furthermore, the spacing between individual interactive elements is often too small, leading to input errors. For an accessible design, it is essential that touch targets have a minimum size and that contrast remains stable even under difficult lighting conditions.
To make the digital transition in retail banking socially inclusive and economically successful, Sparkassen must put the needs of their older, often affluent customers at the center of product development. Minds' Target Audience Simulation allows product and UX teams to test design changes, new features, or alternative navigation concepts in advance using virtual panels.
The advantages of this method are clear:
Speed: Deep UX insights are available in under an hour, instead of after multi-week physical testing phases.
Cost-efficiency: The simulation runs at a fraction of the cost of a traditional panel, as there is no expensive recruitment or compensation for human participants.
Data privacy: The entire simulation runs on EU servers and is 100% GDPR-compliant. No personal data of real customers is processed.
Scientific foundation: Minds' simulation models are based on a three-stage validation model. Data anchoring (Level 01) uses real market studies, the simulation model (Level 02) maps demographic and psychographic behavioral patterns, and validation (Level 03) is performed against established reference benchmarks such as data from the Statistisches Bundesamt or Kantar.
By avoiding rigid assumptions and continuously calibrating against real behavioral data, Minds provides a reliable basis for decision-making when optimizing digital banking applications.
The results of this simulated UX study highlight that the Sparkassen app offers significant potential for optimization for the over-65 target group. To promote the digital financial inclusion of older people while reducing the load on physical branches, Sparkassen should consider introducing a simplified senior mode. Such a mode could feature larger touch targets, high-contrast displays, the elimination of nested menus, and integrated, simplified transaction authorization.
With Minds, Sparkassen and regional banks can test such innovative approaches risk-free and cost-effectively before committing expensive development resources.

How reliable are Minds' simulated UX results compared to real user testing?
Minds simulations achieve an average correlation of 85% to 95% with traditional, physical panels regarding user preferences, language barriers, and objection structures. For specific questions and precisely calibrated segments, validity can even reach 100%.
How quickly does Minds deliver detailed UX analyses for older target groups?
Minds delivers deep, data-driven insights in less than an hour. Unlike traditional market research sprints that take several weeks, the time-consuming recruitment of physical participants is completely eliminated.
How do the costs of a Minds simulation compare to traditional focus groups?
A simulation with Minds costs only a fraction of a traditional panel. Since there are no recruitment costs per participant and the infrastructure is fully automated, Sparkassen and regional banks can allocate their budgets highly efficiently.
Is using Minds compatible with the strict data protection regulations in the German banking sector?
Yes, Minds is hosted entirely on EU servers and is 100% GDPR-compliant. Since no actual personal data of real banking customers is processed or analyzed, data protection risks in the research process are completely eliminated.
