In our example you have seen how you can pay a partial amount with secucard, and the remainder by cash. We have authenticated against the secuconnect API, created a Smart Transaction, prepared it for secucard payment, and executed the actual payment.
There are a lot more things to learn. For instance, you can:
Use a software development kit (SDK);
Select productive or test environments;
Register new devices;
Change the card group;
Work with acceptance points;
Charge a secucard using cash, or cashless;
Gain bonus credit and spend it at the next buy;
Personalize a card;
Lock and unlock a card.
Many of these features are described below.
