Gift cards allow your customers to purchase a 'Gift Code'. That code is emailed to the purchaser who can then give it as a gift. The code is a 100% discount on the pass that is linked to the gift card.
For example if a gift card is created from a 1 Month Unlimited pass, any gift card codes created are only able to be used to 'purchase' (for free) the 1 Month Unlimited pass.
