Around three or four years ago I ditched my wallet and I've never looked back. It has been such pleasure to only have to carry my phone (with credit card and drivers license). One fewer things to worry about and it means I'm really good about always having both my phone and wallet.
With each new phone (4s, 5s, 6s+) I've bought the Hex Wallet case and it's been amazing, the first one was smooth leather and the next two have been a weird fake snake skin texture, but it is the slimmest wallet case I have ever found and it has an open bottom so that all the various chargers and docks connect without issue.
I continue to scan all of my other wallet cards and keep them in a sync'ed photo album. Barcode scanners seem to work just fine on the cards on my phone. I recommend you give up your wallet too.
