You're in control of what rewards you offer your loyal customers. When a customer has earned enough points to be able redeem a reward, they'll be sent an email letting them know. They can then choose to redeem the reward at any time, as long as the reward is still available. When they click to activate the reward in the mobile app, they will be presented with a voucher that they will show to you to redeem the reward. Once the voucher is activated, the customer only has 15 minutes to collect the reward. You'll see the redemption show up in your 'Redemptions' view in your Tyl portal dashboard.
