Frequently asked questions
General questions
Is the app secure?
Yes. Each time you enter your PIN, our variable keyboard changes the order of the numbers, making it the most secure card payment system out there.
Who is the app for?
There is no field where GP tom cannot be used. After all, it is currently used by over 220 different professions and disciplines. The application will be appreciated, for example, by freelancers or small entrepreneurs with smaller transaction volumes who need to accept payment cards occasionally or are often on the move (e.g. at festivals or markets). However, large corporations and multinational companies are happy to use the application.
How is GP tom different from SumUp?
SumUp requires additional equipment that you must pair with a mobile device. Charging it, turning it on, and finally, processing a payment can take a long time. With us, just download the app and you can immediately take payments on one device!
Is there a limit to the maximum transaction amount?
Technical questions
My phone doesn't read my card
Your card may be in the wrong place on the phone. Most phones have a chip on the back that can read credit and debit cards. Start the payment, then slowly slide the card across the back of the phone. When the system reads the card, all four icons will light up in green. Also check out our overview of the most used phones and the location of the NFC chip for reading the card.

The app can be installed from the Google Play Store or AppStore. If your Android device does not have Google Play store services, you can download the package here.
