Frequently asked questions
General enquiries
Is the security adequate?
Together with card associations, we have developed the most secure environment for card payments. Thanks to the dynamic PIN keypad, which changes the position of the numbers, the PIN is entered differently each time, making it impossible to misuse it retrospectively.
Who is the app suitable for?
There is no sector where GP cannot be used. After all, it is currently used by over 220 different professions and sectors. The app will be particularly useful, for example, for sole traders or small business owners with a lower volume of transactions who occasionally need to accept card payments or are often on the move (e.g. at festivals or markets). However, large corporations and multinational companies are also happy to use the app.
How does this solution differ from SumUp?
SumUp’s rival solution requires an additional device that you have to pair with your mobile device. You have to charge it, switch it on, and so the payment process takes ages. With us, you simply download the app and you can process payments straight away, all on a single device!
Is there a limit on the maximum transaction amount?
Technical queries
My phone isn't reading the card
In most cases, this is caused by holding the card in the wrong place on your phone. Phones usually have an NFC chip on the back – so try initiating a payment and then slowly slide your card across the back of the phone. The payment screen indicates that the card is being read; if placed in the correct position, all four icons will light up green. Also have a look at our overview of the most commonly used phones and the location of the NFC chip for reading cards.
Where can I get the app?
The app can be installed from Google Play Store or App Store. If your Android device does not have access to the Google Play Store, you can download the package here.
When will we start supporting other card brands – JCB, Diners, UnionPay?
We will be adding further card types gradually throughout 2025.
Does it support meal voucher schemes?
Yes. We accept all meal voucher cards issued under the Visa and Mastercard schemes. These include: Edenred, Up, Naše stravenka and others.
On which devices can the solution be run?
Any Android device running Android 8.x or later that has an NFC chip. For Apple, this includes iPhone XS and later models running iOS 17 or later.
Does it support apps, iPhones and iOS?
Yes, the app supports iPhone models from the iPhone XS onwards and iOS version 17 and later.
