My girlfriends solution for me not finding my wallet.
Got this as a gift from my girlfriend, it works as a case and a wallet in one

My girlfriend got tired of finding my wallet when I could not, I was constantly being told about the difference between a boy and a girl look. Her idea was that if my wallet was with my iPhone, she could just ring my phone and find it. That plan had limitations as I had to ensure the ringer was turned up being in the case.
Plan also flawed if I mute my ringer and then can not find my wallet and my phone as well. I don't think she planned on that one. I had no idea where she got it from, she just told me to google the brand of phonewallet and I managed to find it on the link above, learnt from her girlfriend that they spotted one with another girlfriend from their work except it was pink, thankfully I got the black version.
Now my girlfriend is happy, with no more searching for my stuff and I got a great gift which I actually use and that does get me points with my girlfriend. We all know the more points you get, the longer you can spend on the web. I may get more points if I score her one I hope, at least I think that is the clue that seems to get mentioned.
End result for me it is a great way to keep my iPhone and wallet together, now I just have to find a solution for my keys. Keyless entry for everything, how soon will I have to wait for that one?
