House Accounts are digital gift cards that come with a bonus. For example, you could buy a $500 account and get $600 in total value ($100 bonus) to redeem at the local business you are supporting. The $500 you pay for the account goes directly to the venue - giving them the funds they need to help operate their business. You then get $600 in credit added to your digital account via the inKind Mobile App.
When you head into the venue that you're supporting, you can use the app to pay for your meal. Simply open the app, enter in your amount due, and hit "redeem".
