Our technology – your security

Our sensors enable real-time, automated recognition and classification of banknotes – worldwide.

Areas of application

The banknote sensors we develop and produce are used in two areas:

  • In cash machines equipped with a deposit function.
  • In tabletop sorting machines used in all places where large quantities of cash are processed and counted, including in central banks, cash centres, post offices, casinos, petrol stations and retailers.

We also supply our technology to third-party customers (OEM) active in the corresponding sectors.

Worldwide currency adaptation

Our banknote sensors are used in around 100 countries across the world – in other words, virtually everywhere where automated cash deposits and processing are done. In order for our sensors to be able to recognise and process different banknotes, they have to be adapted to the corresponding currencies. This is done using a special piece of software – the currency dataset.


However, as the currencies are constantly changing, the currency dataset also has to be adapted accordingly. The software has to cover newly issued banknotes and the latest counterfeiting methods, not to mention the increasingly strict requirements set by central banks.


Technological development

Each generation of our banknote sensors is deployed for up to 15 years and is maintained and kept up to date accordingly. The fourth generation of this technology is currently on the market.

The sensors are evolving constantly when it comes to processor performance, image processing and the amount of memory needed. Since the very first generation, our sensors have been equipped with a full-surface, double-sided sensor system. The second generation was one of the first banknote readers to comply with the euro fitness framework. All sensor generations are used around the world and are not produced for a specific market.

With the fourth sensor generation, we have been able to combine technologies for the first time – sensors can now be reused in both cash machines and tabletop sorting devices. This has opened the door towards the implementation of a modular system.

Functionality of our banknote readers

In a banknote sensor, banknotes are processed in six steps

Recording and bundling of raw data from the individual sensor systems for further processing

Recognition of various banknotes according to currency, value, issue and condition. All of our banknote readers can be used with multiple currencies

Machine-readable security check of individual banknotes

Classification of banknote quality to determine whether they are processed further or paid out again (recycling). This includes mechanical damage and visual defects (e.g. discolouration, stains and graffiti)

Recording of serial number(s) for subsequent tracing of counterfeits or statistical purposes

Classification according to European Central Bank (ECB) standards, for example
