Yes. Our terminal integration software PepperQik was developed specifically for cloud-based POS systems and the use of mobile checkouts (thin clients).

All card data is processed and encrypted directly within the POS terminal or the respective acquirer’s infrastructure. Therefore, Pepper does not process any sensitive payment data.
For communication between the POS system and the payment terminal, Pepper implements all security and compliance standards defined by the respective communication protocol – ensuring secure and reliable data exchange at all times.

Our terminal integration software PepperQik is integrated as a cloud service via REST API. Pepper Library can be integrated in different ways: procedural integration (C) as well as object-oriented integration (C++, .NET, Java).

Depending on your IT setup, you can choose between two Pepper solutions: With PepperQik, we offer the universal interface as a flexible, fully managed cloud solution (SaaS). If you prefer to install Pepper the classic way on each POS PC individually, Pepper Library is the right choice.

To accept cashless payments at the POS, you need a checkout/POS system and a payment terminal. To make payment processing as fast, simple, and secure as possible, the POS and the payment terminal must be able to communicate with each other. This requires communication protocols such as the ZVT protocol to be integrated into the POS software as a checkout interface.

The abbreviation EFT stands for Electronic Funds Transfer and covers all types of cashless payment transactions. We summarise how EFT works in this article.

The term POS terminal stands for point-of-sale terminal and refers to the device used to capture and identify payment data for cashless payments. A POS terminal is also referred to as an EFT/POS terminal, payment terminal, card terminal, or payment device.

Pepper was developed specifically for the POS terminal models, POS systems, and communication protocols commonly used in Germany, Austria, and Switzerland. Beyond that, Pepper is already used in more than 30 countries worldwide.

Many POS software providers have already integrated Pepper into their products as a universal connection to payment terminals. You can find a list of all POS software solutions that include Pepper here.

Our Pepper solutions support more than 100 payment terminal models from 11 different manufacturers. Want to know whether your model is included? You can find out quickly and easily here.

For both the PepperQik cloud service and Pepper Library, you should expect around one week of initial integration effort.

With our Terminal Type Assistant, you can quickly and easily find all supported terminals that we have already tested for compatibility. If you would like to use a different model, please get in touch. If needed, we can run a compatibility test for you.

Yes, that’s possible. The prerequisite is that you have the appropriate Pepper licences. If you have any questions, feel free to contact us at any time.

Yes. In addition to classic card payments, Pepper also supports newer cashless payment methods such as WeChat Pay, AliPay, or Apple Pay. If you have any questions, feel free to contact us at any time.

When it comes to software licensing, we offer our customers two different models: with the fixed model (Pepper Library), you pay a one-time licence fee for the interface to a specific communication protocol, followed by an annual maintenance fee. Additional interfaces require their own licence. Our rent model (Pepper Library & PepperQik) offers maximum flexibility: the month-to-month subscription includes all communication protocols supported by Pepper. If you switch terminals, there are no additional costs.

To test Pepper in your IT environment with no obligation, you can download a free trial licence. Please note that the Pepper trial licence is limited to certain amounts and a defined period of time.

To give you a reliable answer, Pepper Support needs the following information: the POS interface/POS protocol active on the terminal, the name of the terminal provider, and the country where the terminal will be used. If you email us this information, we’ll be happy to answer your question personally.

The Pepper logfile directory is defined in the file pepper_config.xml.

All developer documents and files you need to integrate Pepper are available in the Pepper Support Portal. Simply register and download.

Yes. If you need help with the integration, you can book our Integration Support Service. Just get in touch with us.

Yes, that’s possible. For this, we developed our own software component: the PepperQik Satellite. The Satellite is simply installed in the local network and handles communication in place of the cloud interface.

Yes. Our PepperQik solution was developed specifically for cloud-based POS systems.

To test PepperQik for free, simply register on our test system and you’ll receive a test registration code from us. If you have any questions, you can also contact us directly at any time.

For the initial integration of the PepperQik REST API, you should plan on about one day of work. After that, connecting new terminals takes only about 5 minutes.

By using a REST API, PepperQik works independently of the operating system in use: the cloud service can be called by any modern POS system. For connecting specific endpoints, the integrator receives a standard REST API including documentation with example HTTP requests and responses.

To use PepperQik, you need an internet connection. The cloud service requires at least 100 KB/s for both download and upload.

PepperQik is our cloud solution controlled via REST API. That means PepperQik works with cloud-based POS systems and terminals just as well as with POS systems and terminals that run locally by the retailer.

PepperQik is a cloud software service billed monthly or annually (with a discount). Depending on how many transactions/operations you process per month, you can choose between different plans. PepperQik can scale flexibly as your business grows.

treibauf takes care of hosting, operation, and maintenance of PepperQik.

To integrate Pepper into the POS software as a DLL (library), you should plan on about one week of effort. Connecting new terminals then takes only about 5 minutes.

Pepper Library is our Pepper solution specifically for classic PC-based POS systems. Pepper is integrated into the POS software as a library via the standardised Pepper API.

Here you can find all operating systems supported by Pepper Library.

Because Matchbox provides standardised interfaces, you can easily connect the software to any ERP system.

Yes. As part of the rollout, users receive training from us on how to use Matchbox effectively and get the most out of the software.

You can import your data either as files (fixed-length, CSV, and XML) or as data streams via various APIs.

By combining clearly defined, role-based access controls with a comprehensive audit trail, Matchbox delivers full transparency and audit readiness. All actions and changes are fully documented within the system, ensuring that all relevant records for internal and external audits are always readily available.

Matchbox either provides your reconciled data as an XML file (for sFTP download) or sends it directly to your ERP via web service.

The integration effort depends on how complex your payment processing is. On average, you should plan on around four weeks.

Matchbox is already used in more than 35 countries today.

In the context of Matchbox, reconciliation means matching POS card payments on the one hand with the settlement reports from payment processors on the other.

Matchbox is compatible with common operating systems such as Windows or Linux. Since the software is delivered as a Docker image, it works independently of the underlying operating system.

Matchbox already processes a wide range of payment systems. Thanks to the standardised interfaces, you can also connect other technologies to the software with minimal effort.

You can connect Matchbox to any POS system without issue. In addition, our Pepper solutions provide a standardised interface to Matchbox.

We offer the software as an ASP model (Application Service Provider). Alternatively, you can use Matchbox as a classic on‑premise solution.
