Lost Season Pass Card, Replace vs Just Use Phone App?

As the title says, I somehow managed to lose my physical Platinum Pass card during a recent trip this past weekend. First, does anybody know how long the park keeps items in lost and found on the offhand chance it was picked up? And two, would it be worth pursuing a replacement card when I can pull up the same bar code used for everything in the CP app with seemingly no harm no foul?

Honestly the only disadvantage seems to be that it then pretty much tethers me to my phone for picking up on ride photos via FunPix and such, but I also don't know if there are any contexts within the park where they HAVE to see the physical card.

Due to a mix up at the pass center this spring, I don't have a physical card and have used only my phone (or my Samsung watch) all season with no issues. The only situation I can think of where a physical card may help would be if you're getting the pass discount at a sit down restaurant, where they take your card to a computer station to ring it up.
