All gift cards sold on your Toggle shop or in-venue will be "multi-use" rather than single-use.
This means the gift card's balance can be spent across multiple visits until the balance is used up (or until the gift card expires) as opposed to only being allowed to be used on one visit.
On your Toggle dashboard and reports you'll see the breakdown of each visit and its respective redemption amount, date and time it happened, and the venue it was redeemed at, as exampled below.
