Is there a way to *remove* RFID blocking from my 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.
It may or may not be possible to remove the blocking.
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.
I don’t think it’s a webbing since even the clear plastic portion on the outside is blocking the card from being read. And I know it’s not just the thickness of the material since it could be read through my old leather wallet.

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.
While you can't remove the RFID blocking from that wallet without unsewing it and resewing it together, you can probably have someone customize an extra pocket, or put two elastic bands around it to secure your metro card on the outside of the wallet. Or a hybrid solution where you have someone (or yourself) sew or rivet elastic bands to hold the corners of your metro card onto the wallet, but that seems silly.
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.
Wouldn't the phone interfere with the chip eventually?
Any interference would come from the physical body of the phone rather than the wireless radio. The NFC writer of the phone (if it has one) has to be very specific parameters (including a crypto key) to write on the chip (reading it, apparently, doesn't take a cryptographic key on Clipper Cards). There are folks who even take out the RFID tag from the card and just paste it to their phones. AFAIK, the only thing you have to worry about is physical damage to the chip.
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?
I'm pretty sure most Real Leather (TM) wallet makers will make a wallet that has no RFID protection (which is what I think you are asking, since most minimalist wallets have RFID protection).

folks at my work put their metro cards with their work badges.
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.
I don’t think it’s a webbing since even the clear plastic portion on the outside is blocking the card from being read. And I know it’s not just the thickness of the material since it could be read through my old leather wallet.
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.

Nothing to do with your wallet, just a demo of a Faraday cage

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.

This is a good principle to uphold.

My favorite is the guy who delaminated a commuter card chip, and put it into a "magic wand".
