    “RFID blocking is a scam”

    There is an entire video with that title, and its comment section is full of people agreeing. They have a point:

    “A solution to a nonexistent problem. These products use fear to add to the price.” — “RFID-blocking wallets are not necessary for the average person because the security risks they protect against are rare.”

    We’re not going to argue with that, because the interesting bit is what those same sceptics say next:

    “Someone tested those, they don’t work or work very poorly — use a metallic card sleeve, that is the only thing that works.

    This is a closed steel box. There is no lining, no coating and no claim bolted onto a leather wallet — the shielding is just what a metal enclosure does. Buy it because it’s a good flat card case; the shielding comes free with the shape.

    A test you can run tonight

    Put your hotel key card in your wallet and tap the door

    Leather walletA leather wallet held against a hotel lock, light green
    The lock reads straight through it and the door opens. If that happens, your wallet isn’t shielding anything.
    Closed steel caseThe closed metal case held against the same lock, light red
    Same door, same card, same second. Nothing gets read.

    This is the point — you don’t have to believe us. It’s a ten-second test with a card you already have, and it works on any wallet you own.

    The actual reason people switch

    Getting it out of your back pocket

    BeforeA bulging pocket with a leather wallet
    A folded leather bifold, and everything it accumulates over five years.
    AfterThe same pocket with the slim metal case
    Same jeans, same pocket. It lies flat enough to forget it’s there.
    Six slots, one card per step

    You can see which one you’re taking

    Taking a card out one-handed

    Stacked card holders make you thumb through a block of identical edges. An accordion steps them, so each card has its own visible sliver and its own slot — you pick the one you want and push it out with a thumb.

    Six slots. One card per slot, which is also what stops them rubbing against each other in your pocket.

    And they don’t bend

    A rigid case is a rigid case. Cards inside it don’t curve to the shape of your leg over eighteen months, which is what eventually kills the chip on a bifold card.

    Measuring the thickness
    ThicknessMeasured rather than described — see the honest note below on the number itself.
    On a kitchen scale beside a leather wallet
    WeightMetal sounds heavy. Next to a loaded leather bifold it usually isn’t.
    A thick licence going into a slot
    Thick cardsA laminated licence is the one that catches people out. It goes in.
    What separates this from the $10 version

    The finish, close up

    Macro of the latch
    The latchA machined push latch on the front edge, not a friction fit that loosens.
    Macro of the edge and rivets
    The edgeBrushed grain, rounded corners and two flush rivets on the side.

    Let's be straight with you

    What we can tell you, and what we can’t yet

    What it is

    • Closed stainless steel case with a black brushed finish
    • Accordion interior, six slots, one card each
    • Push latch on the front edge
    • Flat enough for a front pocket
    • Rigid — cards can’t bend inside it

    Not confirmed — so not claimed

    • Thickness in millimetres, empty and loaded
    • Weight in grams
    • Exact steel grade and finish type
    • Tested hinge and latch cycles
    • Any documented blocking test
    • Scratch resistance rating

    There is no cash slot. None. If you carry notes, this is not your wallet and we’d rather you knew that from the product page than from the parcel. Coins, obviously, no.

    We have no lab test for the shielding. A closed metal enclosure attenuates the signal — that’s physics, not a claim we invented — but we don’t have a measured report from the maker and we’re not going to print a percentage. Run the hotel card test yourself; that’s a better answer than a number we can’t back.

    And the risk itself is contested. Contactless fraud by scanning a card in someone’s pocket is rare, and modern contactless cards make it harder still. Buy this because it’s a flat, rigid, well-made card case. If it happens to also stop a reader, treat that as a side effect and not the reason.

    No inflated material language. Every cheap version of this reaches for the same overblown phrase about the steel, and this audience treats that as a sign something is being oversold. They’re right. It’s stainless steel with a black brushed finish — that is the whole description.

    The failure mode worth knowing about

    The documented weak point of this whole format is the hinge, and the complaints are specific: “I bought 3 last year and they all broke the hinge, one after the other.” We have asked the maker for a tested cycle count and don’t have it yet. Until we do, we’d rather flag it than let you find out — and the 30-day return exists precisely so an early failure costs you nothing.

    In their own words

    What this audience actually argues about

    “Use a metallic card sleeve, that is the only thing that works.”
    “Next time you rent a hotel room, try leaving the key card inside your wallet and put it up to the door. If it works, your wallet isn’t protecting you.”
    “Military grade is not a sign of quality but the lowest bidder.”
    “Physically stolen cards is a much higher risk.”

    The hotel test settled it

    I was firmly in the ‘RFID is marketing’ camp. Tried the key card thing on my old wallet and it opened the door. This one doesn’t.

    Finally out of the back pocket

    That was the whole reason I bought it. My back is a separate conversation but the pocket is flat.

    It marks, and no cash

    Both are on the page so I can’t complain, but the matte finish picks up keys quickly. Still using it.

    Questions? We've got answers

    Frequently asked questions

    Does it hold cash?

    No. There is no note slot and no coin pocket at all. If you carry cash regularly this is the wrong product for you and we’d rather say so here than take the order.

    Does the RFID blocking actually work?

    It’s a closed metal case, and a closed metal enclosure attenuates the signal — that’s the physics, and it’s why even people who call RFID wallets a scam recommend metal. What we don’t have is a measured test report from the maker, so we won’t quote a figure. Do the hotel key card test yourself.

    Isn’t RFID theft mostly a myth anyway?

    Largely, yes — it’s rare, and modern contactless cards are harder to abuse than the marketing suggests. We think you should buy this because it’s a flat, rigid card case that gets your wallet out of your back pocket. The shielding is a side effect of it being made of steel.

    How many cards does it hold?

    Six slots, one card per slot. Two cards forced into one slot is how people break accordion cases, so we don’t recommend it.

    How thick is it, and how much does it weigh?

    We haven’t had those figures confirmed by the maker and we won’t print numbers we can’t stand behind. We know that’s the question this audience cares most about — email us and we’ll tell you exactly what we have.

    Will a thick driving licence fit?

    Yes, a laminated licence goes into a slot — there’s a photo of exactly that on this page. Heavily embossed cards with raised numbers can be a tighter fit; ask us if that’s your main card.

    Will it scratch?

    Yes, over time. It’s a matte finish and it lives in a pocket, often with keys. There’s a photo on this page of it beside a keyring rather than a promise that it stays perfect.

    What about the hinge breaking?

    That’s the documented weak point of this format and we’ve flagged it openly above. We’ve asked the maker for a tested cycle count and don’t have it yet. If it fails inside 30 days, send it back for a full refund.

    Can I use it left-handed?

    The accordion opens the same way regardless, but which hand it suits best is worth thinking about. Tell us you’re left-handed when you order and we’ll tell you what other left-handed customers have said.

    Will my card still tap while it’s inside?

    No — that’s the whole point of a closed metal case. Take the card out to pay. If you want tap-through-the-wallet convenience, you specifically don’t want a metal enclosure.

    What’s shipping like?

    Orders ship within 24–48 hours with tracking, typically 5–7 business days in the US.

    Stainless steel card case with an accordion interior, six card slots. No cash or coin compartment. Shielding: the case is a closed metal enclosure, which attenuates radio-frequency signals as a consequence of its construction. No independently measured or certified blocking test has been supplied by the manufacturer, and no attenuation figure, percentage or standard is claimed anywhere on this page. Contactless card fraud by remote scanning is uncommon and modern contactless cards incorporate their own protections; this product is sold as a card case and is not a security device, not a guarantee against fraud or theft, and no protection against physical loss or theft of cards is implied. Cards must be removed from the case to be tapped. Not confirmed by the manufacturer and therefore not stated: thickness, weight, steel grade and finish type, tested hinge and latch cycle count, and scratch resistance. The hinge is the documented failure point of this product format; contact us before purchase if longevity data decides your order. The matte finish will mark with normal pocket use. Keep away from small children — the case has a sprung latch and small parts. Colour and finish may vary slightly from the images shown. Reviews reflect individual experiences.
