Pepper Library is our Pepper solution developed specifically for traditional, PC-based cash registers. The universal interface makes it easy to connect more than 100 different POS terminals – and therefore grants you greater flexibility when it comes to EFT/POS.

What IT environment has Pepper Library been developed for?

Pepper Library is used for traditional, PC-based cash registers. Pepper is integrated into the cash register software as a library via the standardised Pepper API.

Pepper Library can therefore be integrated into all commercially available cash register software solutions that, as a rule, are also able to function without a network connection (thick clients). We have developed Pepper Container for mobile cash registers (e.g. Android cash registers).

In the case of Pepper Library, the POS terminals are connected via the communication interface available on the terminal (TCP/IP, serial, etc.). We have provided a detailed description of how this connection works in the Pepper Developer Portal.

How implementation works

In order to integrate Pepper Library into your cash register software, you must first download the Library, the developer document and a free trial licence from the Pepper Developer Portal.

Next, follow the instructions in the developer document to implement the Library within your cash register software.

Should you require assistance, you can also book our Integration Support Service, where a treibauf Supporter will personally walk you through the implementation process.

Once you have implemented the Pepper Library within your cash register software, you can start by checking whether you have seamless communication with the POS terminal, free of charge.

Once everything is up and running, all you have to do is order your product licences for permanent use and sign a usage agreement with treibauf.

Fix or Rent licence?
The choice is yours!

When it comes to licensing the software, we offer our customers two different licensing models:


You pay a one-off licence fee for the interface with a specific communication protocol followed by an annual maintenance fee. Further interfaces with other communication protocols require additional licences.



Our Rent model offers you maximum flexibility. This is because the rent, which can be cancelled on a month-to-month basis, includes all of the communication protocols supported by Pepper. This means that you will not incur any additional costs if you change your POS terminal.

Would you like to learn more about our licensing models? We will be happy to provide you with information and advice at any time. Simply get in touch with us directly.
