About this piece
This slim metal card wallet is a minimalist alternative to the leather bifold. Push the side lever and the cards fan out in a neat arc. Pull the one you need and push the rest back, all with one hand.
Quick answer: the Slim Metal RFID Blocking Card Wallet is an aerospace-grade aluminium card wallet with built-in RFID blocking. A one-handed pop-up lever fans 8-12 cards out in an arc, and the sealed metal shell is designed to block contactless skimming at 13.56 MHz. At 70g it weighs about half as much as a typical leather bifold. It suits front-pocket carriers, commuters and minimalists.
Why choose a metal card wallet over a leather bifold
A metal card wallet beats a leather bifold on weight, bulk and built-in RFID protection. Leather wins on patina and a traditional look.
- Half the weight: the aluminium card wallet weighs 70g, against 120-180g for a typical leather wallet.
- Half the bulk: it is 1.2cm thick closed, against 2.5cm for a stuffed leather bifold.
- RFID protection built in: no foil sleeves to add.
- No stitching to fail: leather wallets fail at the corner stitching first, and aluminium has none.
- Every card equally accessible: there are no interior pockets to fight with, because the fan-out shows every card.
The case against: the aluminium does not develop patina the way leather does. Some people see leather patina as a feature, others as scratched-up wear. If patina matters to you, look at our leather options instead.
How the pop-up mechanism works on this aluminium card wallet
The pop-up mechanism works by a spring-loaded rail inside the shell that pushes the cards up from the bottom when you press the side lever. The cards fan out in a clean arc, each offset slightly from the next, so you can see and grab any of them.
After use, push the cards back into the shell and they sit flat. The mechanism is rated for 10,000+ cycles before any noticeable wear.
For contactless payments it is faster than a leather wallet: lever, present card to reader, return. A leather bifold means opening it, finding the right slot and sliding the card out, which is slower in the rain or in a hurry.
How the RFID blocking metal wallet protects your cards
The RFID blocking in this metal wallet comes from the aluminium shell, which is designed to act as a Faraday cage: a closed conductive surface that stops radio frequency reaching the cards inside. It is designed to block 13.56 MHz, the frequency UK contactless cards use (ISO/IEC 14443 standard). Skimming devices read that frequency from up to 10cm away and copy card details for fraud. We have not run independent lab tests on it.
The protection is passive: no batteries, no electronics, no app. The shell is the shield, and cards work normally once you take them out.
How many cards the metal RFID card holder carries
The metal RFID card holder carries 8 cards comfortably with the full pop-up function, and up to 12 at most. At 8 cards, the lever fans them in a clean arc. At 12, the fan-out is slower. An elastic cash strap on the back holds 3-4 banknotes folded in half, or 8-10 folded into thirds.
Who the slim metal RFID card wallet suits
The slim metal RFID card wallet suits anyone who wants less bulk in the pocket.
- Front-pocket carriers: the 1.2cm profile does not bulge.
- Daily commuters: fast contactless access, with RFID protection on crowded transport.
- Travellers: slim enough to keep in a passport holder, and it protects all cards from skimming.
- Minimalists: fewer items, fewer cards, faster access.
- Gifts for men with overstuffed leather wallets: the upgrade they did not know they needed.

How to look after the aluminium card wallet
Look after the aluminium card wallet by wiping it with a slightly damp cloth. Avoid abrasive cleaners, as they dull the anodised finish over time. The mechanism needs no lubrication. If it jams (rare, usually caused by overstuffed cards), open it carefully, slide the cards out and fan them out again. It almost always self-corrects.
If an item arrives faulty or not as described, you are entitled to a repair, replacement or refund under UK consumer law.
Questions answered
Does the RFID blocking actually work? +
Yes, the aluminium shell creates a Faraday cage around the cards. It is designed to block 13.56 MHz (the standard UK contactless card frequency, ISO/IEC 14443). We have not run independent lab tests on it.
How is RFID blocking different from card sleeves or aluminium foil? +
Card sleeves protect one card at a time and slide easily out of place. Aluminium foil works but isn't sustained by use. A sealed metal wallet (this one) creates a continuous shield around all cards simultaneously, with no chance of misalignment. The protection is built into the shell, not bolted on.
How many cards does it actually hold? +
8 cards comfortably with the full pop-up function (the lever fans them in a clean arc). Up to 12 cards if you don't mind the fan-out being slower. Common configurations: 8 = debit + credit + Oyster + work pass + driving licence + 3 loyalty cards. 12 = above + 4 more loyalty/membership cards.
Is it heavier than a leather wallet? +
Lighter, 70g vs 120-180g for a typical leather bifold. The aluminium is genuinely thin (1.2cm closed) so it sits flatter in a front pocket without bulging.
Will it scratch my cards? +
No, the interior of the shell is smooth-finished. Cards slide in and out without abrasion. The pop-up mechanism uses a spring-loaded rail that pushes cards from the bottom, not a friction wheel that could wear card surfaces.
How does the cash strap work? +
An elastic strap on the back of the wallet holds 3-4 banknotes folded in half, or up to 8-10 if folded into thirds. UK £5/£10/£20/£50 notes all fit; the strap stretches to accommodate currency wider than the wallet itself (US dollars, Euros).
Will it set off airport metal detectors? +
Yes, like keys, watches, or any pocket metal, you'll need to put it in the tray at security. Not flagged as suspicious, treated like any other metal personal item.
Is the metal wallet better than a leather wallet? +
Different rather than better. Metal wins on: weight (70g vs 150g), bulk (1.2cm vs 2.5cm folded), RFID protection (built-in vs added), card capacity per cm. Leather wins on: classic aesthetic, develops patina, holds folded receipts/notes more securely. For minimalist function, metal. For a more traditional pocket aesthetic, leather.
What if it arrives faulty? +
If an item arrives faulty or not as described, you are entitled to a repair, replacement or refund under UK consumer law. Light scratches on the anodised finish from normal use are not a defect.
Suitable as a gift? +
Yes, particularly good for: minimalists upgrading from a bulky leather bifold; tech-leaning gift recipients; men who carry their wallet in their front pocket; commuters who use contactless multiple times daily.
