A coupon and voucher are two types of rewards in a mobile loyalty program.

A coupon is a type of discount that can be redeemed for a specific product or service. It is typically offered to customers as a promotional incentive to encourage them to make a purchase. Coupons can be redeemed in-store or online and often have a expiration date.

A voucher, on the other hand, is a pre-paid certificate that can be redeemed for a specific product or service. Unlike coupons, vouchers can be redeemed for a specified value and can be used at any time until their expiry date. Vouchers can also be used to purchase a range of different products or services, making them more flexible than coupons.

In a mobile loyalty program, customers earn coupons or vouchers for making purchases, referring friends, or participating in other promotional activities. These rewards can then be redeemed for discounts on future purchases or for other benefits, such as free shipping or exclusive access to new products.
