Years ago when I went to Planet Fitness I didn't like their app and it was slow to load the barcode I needed to scan to get in. Thankfully that barcode didn't rotate so I was able to just make my own Apple Pass and set it up to be geo-fenced on the gym so as I walked up it would pop up as a notification I could tap to open my code.

I love being able to do things like this and rip out the crap being forced down our throats.
