A Dual Access Coupon (DAC) is equivalent to a month of subscription. Think of it as a digital coupon that you can use to gain 30 days of subscription time or transfer to another player.
To view your DACs, use or send a DAC to another player, you will need to access the DACs tab in your account page: https://www.dualuniverse.game/account/dacs
The initial set of DACs being released has already been purchased by our Kickstarter backers through the Founder and Supporter packages. You can however receive DACs from any player who has already purchased them, for example in exchange for quanta, allowing you to buy Dual Universe game time using your in-game assets, or to gift game time to friends.
