The Iaido Series Card Coin Wallet Might Finally Solve Coin Storage
Taiwanese brand Liv-n is bringing an auto-sorting coin wallet to crowdfunding.
I want to tell you about a wallet that popped up on my Instagram feed recently, because it stopped me mid-scroll. Not because of slick branding or a flashy campaign video, but because it is built around an idea I have genuinely been waiting to see someone execute for years - an idea i once had but never had the skills to bring to life.
When I got my first bank account as a kid, the bank threw in a coin sorting machine as a freebie. You fed a coin into a slot, it ran down a narrow chute, and dropped automatically into the correct compartment depending on its size. It was a simple device but I was genuinely obsessed with it. That satisfying, mechanical logic, every coin finding its own place without any intervention - has stuck with me ever since.
Fast forward to a few years ago and I found myself thinking about coin storage in wallets. It is an area that has seen almost no meaningful innovation. The options have always been the same: a zip pocket, a press-stud compartment, or just throwing your coins into a loose section and hoping for the best. Nothing has ever really improved on that. When I started brainstorming what a genuinely innovative coin storage solution might look like, that childhood coin sorter kept coming back to me.
I never did anything with the idea. But it turns out someone else did.
Meet the Iaido Series Card Coin Wallet
The Iaido Series Card Coin Wallet is the debut product from Liv-n, a new Taiwanese design brand. The campaign has not yet gone live but is heading to Zeczec, the Taiwanese crowdfunding platform, with a pre-order survey already circulating to gauge interest and gather feedback ahead of launch.
The headline feature is exactly what it sounds like: an auto-sorting coin mechanism. As you insert coins, they drop into categorised slots automatically, sorted by denomination without any manual effort. It is the coin sorter from my childhood, miniaturised and built into a wallet. There is also a quick-release function that ejects coins cleanly when you need them, which neatly solves the other classic coin wallet problem: fishing around for the right coin while holding up a queue.
Beyond the coin mechanism, the Iaido is described as an all-in-one carry: coins, notes, and cards in a single wallet. The shell is anodised aluminium, described as scratch-resistant and lightweight, with a safety lock that engages when the wallet is open so nothing falls out if you drop it. Despite holding more coins than a conventional wallet, Liv-n claims it sits within the footprint of a standard short wallet.
Who Is this Wallet Actually For?
This is the honest question worth asking, because the answer depends heavily on where you live. In the United States and much of Western Europe, coins have been in steady decline for years. In the UK, contactless and mobile payments have all but eliminated the need to carry change for most people. The days of needing exact coins for a bus fare, a parking meter, or a vending machine are largely behind us in most Western cities.
The fact that Liv-n is a Taiwanese brand is relevant here. Cash, and particularly coins, remain a dominant form of payment across much of Asia. Japan, Taiwan, South Korea, and other markets still rely heavily on physical currency in everyday transactions in a way that has largely disappeared in the West. For those users, a wallet designed around efficient, organised coin storage is not a novelty - it is a genuine practical tool.
What We Do Not Know Yet
Information on the Iaido is still scarce. What is out there amounts to a short video, some early images, and the pre-launch survey that outlines the intended feature set. Pricing, full specifications, and a confirmed launch date have not been announced. The campaign is launching on Zeczec rather than Kickstarter, which means it is likely aimed primarily at Asian markets first, though international backers should be able to participate.
What do we have is the size of the wallet coming in at 2.2cm (D), x 12.3cm (L) x 7.5cm (W). As was my initial thoughts this is a big old wallet and honestly, that’s no fault of the designers. Coins are big coins are bulky and creating a mechism like this for storage is going to require a larger size wallet - much bigger than normal.
The big unknown is how well the auto-sorting mechanism actually works with coins from different countries, which vary significantly in size, weight, and thickness. A mechanism calibrated for Taiwanese coins may behave differently with US quarters or Euro denominations. The wallet also has only 4 slots for sorted coins while most countries have significantly more coin dimoniations than that. Is this 4 slots for just the highest value coins? What about other coins? Are they just disregarded? All questions we’ll know more with time. That is the kind of detail that only becomes clear once the product is in people’s hands.
Early Verdict
The Iaido Series Card Coin Wallet is doing something I have genuinely not seen done before in this space. Coin storage in wallets has been stagnant for as long as I can remember, and the auto-sorting concept is a legitimate leap forward in thinking, assuming the execution holds up.
Whether it finds a Western audience is a separate question from whether it is a good product. For the right market, this is exactly the kind of thoughtful, mechanism-driven design that the wallet space needs more of. I will be watching the campaign closely and will report back once it goes live on the 16.03.2026. Keep track of things on their instagram using the link below.
