应用程序喜欢火种，如何永远不会显示相同的卡？

not sure if this is the right place to ask this, I am making an app that works kind of like tinder as in it has cards that you can swipe left or right on, however I can't figure out how I would never show the same card more than once to a user, would I have to have like a true/false value in a database? not sure if this is the right place to ask this
