What checksum offers

To the products

We relieve you

With us, you get everything from a single source. We advise you and ensure that you have a complete solution at the point of sale. We work in the background with various payment processors such as PostFinance, Worldline and Nexi. We organise the entire activation process and relieve you of all the paperwork with the payment processor. Our aim is to make your life as easy as possible.

Everything on one device

When you order a checksum payment device, you don't need any additional infrastructure because you can use the payment device for cash and card payments, as a cash register with or without a receipt printer. This saves you a lot of money and nerves, as you don't need any additional expensive checkout infrastructure.

Everything on one portal

With the checksum portal, you can track your sales performance in real time. You have a view of all payments, with no restrictions on certain payment cards. You have access to all statistics, which you can send to your trustee in an Excel file. You can also see the VAT, which will help you with your quarterly tax return.

Many advantages

Favourable and simple

The payment device becomes the cash register and you need less hardware. This is cheaper to procure and also requires no technical integration. You switch on the device and it works immediately.

Upgrade or downgrade possible

Not sure if you need a cash register? No problem. If you want, you can first order a device without a cash register (Basic) and then upgrade to a Pro at a later date. The reverse is also possible.

Central article management

You can manage the articles centrally, e.g. on a PC, and the changes on your devices are visible in real time. No tedious app synchronisation is required.

No long cancellation periods

You can simply cancel your contract with checksum by telephone, e-mail or letter post within one month.
