I recently bought this wallet:

The RFID blocking wasn’t even a main selling point, I just liked the wallet. Unfortunately it blocks my metro card from working at kiosks forcing me to pull it out every time which is annoying. I was hoping the clear side wouldn’t block it but no such luck.
I don’t know the details of how blocking works and haven’t had any luck searching for solutions since, understandably, most people want the opposite.
Otherwise I’ll just have to go find a new slim wallet.

I would expect that the wallet is acting like a Faraday cage, meaning the content is kept in a metal case or metal webbing so that metal may or may not be possible to remove. Try and see it there is some sort of inner liner in the wallet pockets that can be removed.
Nothing to do with your wallet, just a demo of a Faraday cage

I had a wallet with this feature that just fell apart. It seems like they just put foil inside of the sewn parts of the wallet. Unless you can unseam part of the wallet and resew it, I don't think you can remove it.
If you don't have a phone case, or your phone case is something you can replace, I believe there are phone cases that can hold transit cards snugly. I've seen people use those for BART.
Don’t know why I hadn’t thought of this. The card easily fits in my phone’s case. Gonna test it out after work.
EDIT:
Like, holy shit, people have taken Clipper cards (SF's metro card) and melted it in acetone, then took out the chip and the antenna loop and embedded them into jewelry and shit.

I think I’m just gonna have to cave and get a different wallet.
Edit: new question. Does anyone even sell a minimalist wallet that does have RFID protection?
They may be under a different name, though:

Depends on what aesthetic you are going for. I'm quite pleased with the few Hide and Drink products I've bought.
Now to play the waiting game.
Quid, be sure to report back on how it works!
Outside is leather and the inside is rip-stop parachute material.
This here is the real solution, melt down your card and turn it cast it into the snake head of your cane.

I refuse to wear my work badge while commuting on principle.
I tack my train cards to my work badge so I can never leave without both, and just keep the train cards in my pocket during work. This is very specifically so I can't get on the train without my badge though.
This is a good principle to uphold.
Late to the party, and a less good solution than the new wallet, but:
Transparent shielding is apparently a thing, so you could probably buy a sheet of normal plastic, cut out the old window, and super glue the non-interfering stuff back in place.
(But having to slap your open your wallet on the scanner several times a day sounds like a recipe for disaster)
I believe passive RFID works by how radio waves interact with magnetic fields, which creates power for the chip on the card to transmit back to the reader. By blocking just a single side of the wallet it can interrupt the magnetic power transfer, and there stop passive rfid devices from working.
If it was active RFID, meaning the rfid tag is powered on it's own, that wallet probably wouldnt stop anything from transmitting through the clear plastic.
My favorite is the guy who delaminated a commuter card chip, and put it into a "magic wand".
