Pattern for displaying payment of product with point system such as frequent flyer points.
So the customer is buying a product for $300 and on the payment screen has the option to pay for this with points. However, he only has enough points to pay $100 off the price. This is basic display of managing how many points to use...
(POINTS) ===========|--------------------------- (DOLLARS)
478pts = $100 ................................................ $200
As for the actual payment breakdown
PAYMENT SUMMARY
Product X............................. $300
Points (478pts)..................... $100
Payable................................ $200
The display of whats going to be charged to their credit card, don't think its quite clear yet... any suggestions or examples of where this is done. I have never used a point paying system so I am struggling to find examples.
