You're stating that when a customer makes a purchase, a script will run that basically makes an order to buy incent and send it to the customer. So the retailer is buying incent automatically and sending it to the customer?
What happens if the customer never uses the incent?
Then the retailer has sent money to the customer which they will never use. The retailer can't get the money / incent back!!
Am I missing something???
This is essentially what happens, yes. A percentage of the purchase amount it used to buy Incent for the customer. The merchant has known, fixed costs up front (which they love) and no forward liability. The customer gets a digital asset they can use in whatever way they want - spend, sell, hold, give away whatever.
You have to shift your perception of loyalty a little to understand how powerful this is because it's fundamentally different from the IOU-based model of traditional loyalty.
