What are my needs and requirements?

Choosing the right device will depend on the needs and requirements of your business. Consider the following things when deciding:

  • will the device be used all year round, or do you only need it for specific occasions such as trade fairs and events? Or do I a need a device for different situations?
  • Do I want to connect the device to my existing checkout/IT infrastructure, or do I want it to be separate?
  • Where in the store do I want to be able to use the device?
  • How many business locations do I want to use the device at?
  • How many transactions and how much in revenue do I expect to process using the device?

What sort of device makes the most sense for my business?

There are generally two different types of payment terminal:

Devices incorporated into the checkout system

These devices are suitable for companies with higher transaction volumes, and are connected to the checkout system They are installed in a fixed location, which is usually in the checkout area.

Mobile terminals

These are suitable for companies that want to collect payments from the customer directly, for instance: collecting payments from diners at the table itself, in a taxi at the end of the journey, in the customer’s home when providing a service (e.g. chimney sweeping) or at markets and trade fairs, wherever these might be.

Mobile payment terminals can also be used integrated into the cash register. The checkout solution communicates with the mobile terminal over an interface so that the payment amount doesn’t have to be entered, but is instead shown directly to the customer.

What costs do I need to bear in mind?

Acquisition costs

Depending on the provider and product, you can either buy or rent payment terminals. In addition to the rental or purchase price, you may also incur activation and set-up fees or installation fees.

Maintenance costs

Maintenance costs are associated with certain packages, which include, for instance, a replacement service for defective devices, a hotline for questions or software updates.

Transaction costs

Each transaction made using a given device will incur transaction costs. These are either offered at a fixed rate as part of a package, or they can be negotiated with individual acceptance partners.
