SCPCart
Objective-C
@interface SCPCart : NSObject
                Swift
class Cart : NSObject
                An SCPCart object contains information about what line items are included in
the current transaction. A cart object should be created and then passed into
Terminal.shared.setReaderDisplay(), which will display the cart’s contents
on the reader’s screen.
The SCPCart only represents exactly what will be shown on the screen, and is
not reflective of what the customer is actually charged. You are
responsible for making sure that tax and total reflect what is in the cart.
Note
Only Internet readers support setReaderDisplay functionality
- 
                  
                  
You can add or remove line items from this array individually or reassign the array entirely. After making your desired changes, call setReaderDisplay to update the cart on the reader’s screen.
