MagSafe wallet for only one card?

So I’m back to school and I’ve been using the metro a lot to move to and from school. Through this summer I’ve started carrying less and less things and ended up with only my keys my AirPods and my phone on me wherever I go.

The thing is that now I need my transit card which can not be added in the wallet app nor any third party app, I don’t like having it wobbling around in my pocket and I don’t want to carry my entire wallet for just the transit card.

Is it a good choice to get the MagSafe wallet just to have the transit card with my phone at all times?
