A Complete Multi-tender Sale
This chapter lets you catch your breath a bit by providing a review of all the topics that have come before. Specifically, the sample code provides a complete implementation of a sale, from initialization of the EposSDK object right through to a Sale Response. The only wrinkle here is that we now demonstrate a sale where the consumer pays with both cash and card. (They're a bit tight for cash!). So the example shows how to put 5 € onto a card and 5 € on cash. Not so likely in the world, but a great review of what we have learned so far.

Here's a summary of the user interaction where they pay 5 € cash and they put 5 € on a credit card:
