It is same way you redeem offers or the old stamp rewards.

 Scan your App at front counters, Kiosks or Drive through, and tell the restaurant team that you want to redeem the rewards. OR you can add the reward to basket directly if you are using Mobile Ordering or KFC Delivery.

You can only redeem 1 reward at a time.

There is no minimum spend for redemption at Front Counter or Drive Through.

You can check your reward balance and expiration dates on KFC App or online here
