For years, people have been hearing the same prediction: cash is on its way out.
Yet despite the rise of contactless payments, mobile wallets and banking apps, millions of Europeans still carry notes and coins every day. In countries such as Germany, cash remains a normal part of everyday life, whether it’s paying for a coffee, shopping at a local market or settling a restaurant bill.
That may be why Germany is already thinking about what physical money could look like in the future.
A concept developed by the Bundesdruckerei, the German federal printing company responsible for producing highly secure documents, is attracting attention for one reason. It looks nothing like the banknotes people use today.
Called STELLA, the concept note is roughly the size of a bank card and includes a range of advanced security features. It is not scheduled to enter circulation and there are currently no plans to replace euro banknotes with this design. Even so, it offers an interesting glimpse into how cash could evolve in a world where digital payments continue to grow.
Why Germany is experimenting with a different kind of banknote
Take a look inside most wallets today and you’ll notice something that would have seemed unusual twenty years ago.
Many people carry more cards than cash : Loyalty cards, bank cards, driving licences and health cards often take up most of the available space, while banknotes are folded into whatever room remains.
The STELLA concept appears to start from that reality.
Rather than asking people to carry bulky notes, the idea explores whether cash could fit more naturally into modern wallets by adopting a format closer to a payment card.
At first glance, it looks more like something you would pull from a card holder than from a traditional wallet. Its compact size is one of its most striking features.
The concept is part of a broader effort to explore how physical money might remain practical and relevant in the future, even as payment habits continue to change.
That does not mean existing euro notes are disappearing, far from it. The project is simply exploring possibilities rather than announcing a replacement.
The security features hidden inside the concept
Security has always been one of the biggest challenges when it comes to banknotes. The more sophisticated counterfeiters become, the more sophisticated security features need to be.
That challenge is reflected in the STELLA design.
According to information released by Bundesdruckerei, the concept incorporates several technologies intended to make forgery more difficult.
Some security elements would only become visible under infrared light. Other features rely on optical effects and specialised printing techniques designed to be difficult to replicate.
The concept also explores the possibility of integrating an ultra thin chip.
Another detail has attracted attention for a different reason.
Small notches along the edge of the note would help blind and visually impaired people identify it more easily by touch. The feature echoes accessibility solutions already used on coins and modern banknotes around the world.
The aim is not only to make the note secure but also easier for everyone to use.
Will card sized banknotes ever become reality?
That remains a very open question.
At the moment, STELLA is a concept rather than a future currency.
No launch date exists. No decision has been taken by the European Central Bank. No plans have been announced to replace the euro notes currently used across the eurozone.
There are also practical questions that would need answers.
How would such notes be produced on a large scale? How durable would they be? Would people actually prefer them to traditional cash? And how would they work across countries that share the euro?
For now, those questions remain hypothetical.
What makes the project interesting is not that it signals an imminent change, but that it shows how governments and security experts are thinking about the future of physical money.
The debate around payments often focuses on digital technology. Yet projects like STELLA suggest that cash is still very much part of the conversation.
For the foreseeable future, the euro notes in people’s wallets are not going anywhere. But if a future generation of banknotes eventually arrives, it may look very different from the cash Europeans have known for decades.
