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
Ve většině případů je způsobeno přikládáním karty na nesprávné místo vašeho telefonu. Telefony mají NFC čip obvykle na zadní straně telefonu – zkuste tedy iniciovat platbu a poté pomalu posouvejte kartou po zadní straně telefonu. Na obrazovce platby se indikuje načítání karty tak, že v případě přiložení na správné místo se rozsvítí všechny čtyři ikony zeleně. Také se podívejte na náš přehled nejvíce používaných telefonů a umístění NFC čipu pro čtení karty.
