Add cards to Apple wallet

I like the app it works great. I just wish I could just tap to open instead of opening the app and logging in and then wait for the locks to open. If the app had an apple wallet extension I think it would be better

Kills battery

The app prevents the screen from locking so it just kills your battery. There is 0 reason for it to prevent screen lock, unless they do it to invade your privacy and track you.

Convenient Key Companion!

This system makes it so easy to carry your key to your apartment and you never seem to forget it because most of us have our phones on us all the time!

Super convenient!!

So easy when we return to our campground. We don’t have to wait while other campers check in. Works smoothly each time. Love it!
