Integrated card terminals (Viva, Nexi/Verifone, SumUp and more)
The till sends the amount to the card terminal and gets approved/declined back automatically: no typing the amount twice, no wrong amounts. Refunds and cancels through the terminal too. Each shop links its own terminal account in the dashboard and pairs terminals with tills; the shop keeps its own contract and fees.
Order: we start with the terminals Finnish shops use most (research first), then expand. Manual confirm keeps working with any terminal in the meantime.
