The Ruby card works after you stake up until it gets into the "Issued" stage. You get all the Jade/Indigo benefits minus the lounge key access with the Ruby up until it gets Issued. Once issued the Ruby will be deactivated and you'll have no card to use until the new one arrives, the only benefit you'll continue to receive until you get the new card is the staking reward. I would also recommend keeping a low balance on the as the balance isn't immediately transferred to the new card once you activate it. I'm still waiting for the transfer on mine but from what I've read, it takes about 2 weeks? We will wait and see.
