Spinek is a spinning NFC keychain. Tap it to the back of a phone and your link opens: your Instagram, TikTok, Linktree, LinkedIn, booking page or Google review form. No app needed to open the link, no QR code to scan, nothing to hand over.
Hand assembled in Lake Zurich, Illinois. Every Spinek is tested and paired with a setup instructions link before it ships. Small imperfections are normal: each one is made by hand.
Rewritable NFC chip: NTAG213, sealed inside the body during printing. No battery, nothing to peel or charge. Holds a link of about 130 characters and can be rewritten about 100,000 times.
Real bearing: 6704-2RS with chrome steel balls and races, rubber sealed on both sides. Hook a finger through the middle and flick it.
Size: 55 x 34 x 5 mm (2.2 x 1.3 in), about the length of a house key. Matte black, pebble textured PLA body. Four navy arcs mark the tap spot.
Included: steel split ring. The back is laser engraved SPINEK, Pat. Pend.
Works with: iPhone XR, XS and newer, and Android phones with NFC switched on. Thick, metal or magnetic phone cases can block the tap.
You set your link once with a free NFC app like NFC Tools, and change it whenever you want. No account, no subscription. Step by step: setup guide.
Ships from Lake Zurich, IL in 2 to 5 business days. US shipping is $3.99, free on orders of $25 or more. 30-day returns.

Rewritable NFC chip
Hand assembled in Illinois
Built, not printed and hoped for
It spins like something that cost more.
A genuine 6704-2RS sealed steel bearing, the same type used in machinery, locked between the two halves of a matte body. Not a plastic pivot. It has weight to it, the flip is quiet, and the split ring is steel — so it lives on your keys instead of in a drawer.

What people point it at
One tag. Whatever you need it to be.
It's a rewritable NFC tag that already lives on your keys, so it can point anywhere a link can go — and you can change your mind as often as you like.

Anything with a URL works. If you can paste it into a browser, the Spinek can point at it.
How it works
Three seconds, start to finish.
01
They tap it
Hold the spinner near the top of any phone. The wave mark shows exactly where the chip sits.
02
Your link opens
LinkedIn, Instagram, your booking page, a review form, a menu — whatever you point it at.
03
Change it whenever
Rewrite it yourself with a free app, up to 100,000 times. Point it at something new whenever you want — no account, no subscription.
Cheaper than the cards you keep reprinting.
One tag, rewritten as often as you like. Navy & Black is the launch colorway, hand assembled and shipped from Lake Zurich, Illinois.
No. Tapping it needs nothing at all. iPhone XR, XS and newer, and Android phones with NFC switched on, read the tag natively, with no app and no setup.
The one time an app is involved is when you write your own link onto the tag. For that we recommend NFC Tools, a free third-party app on the App Store and Google Play. It isn't ours and isn't affiliated with Spinek. It's just the one we've found simplest. Full walkthrough on the pairing page.
Does it need charging?
Never. There's no battery and nothing to plug in. The chip is passive — it draws the tiny amount of power it needs from the phone that's tapping it, which is why a tag works the same on day one and in ten years.
What happens if it gets wet?
The chip is sealed inside the body and has no battery, so rain or sweat won't stop it working. It isn't rated waterproof, so don't plan on swimming with it.
The bearing is the part that minds. It's steel, so repeated soakings will eventually rust the balls and the spin will get gritty instead of smooth. The tag keeps working, you just lose the nice flick. If it gets properly wet, dry it off and it'll be fine.
Can I change where it points later?
Yes, as often as you like. The chip is a rewritable NTAG213 — write a new link over the old one any time. No account, no subscription, nothing that expires, and these chips take somewhere around 100,000 rewrites.
What can I point it at?
Any URL: LinkedIn, Instagram, a Linktree, a booking page, a Google review link, a YouTube video, a Maps pin. On Android it can also carry a contact card or your Wi-Fi details. On iPhone, point it at a page with your contact or Wi-Fi info instead.
How big is it?
55mm long, 34mm wide and 5mm thick, about the length of a house key, and thin enough to sit in a pocket without a bulge. The bearing is a 6704-2RS sealed steel unit, the same type used in machinery, and a steel split ring is included.
How fast does it ship, and what if I don't like it?
Every Spinek is made to order in small batches in Lake Zurich, Illinois. Orders ship within 2-5 business days, and USPS delivery usually takes another 2-5 business days. US shipping is $3.99 flat, and free on orders of $25 or more (the 2-pack ships free).
If it turns up damaged, or the chip won't read, tell us within 30 days and we'll replace it. You don't need to send the old one back. Changed your mind? Return it in resellable condition within 30 days of delivery for a full refund of the product price. Details in the refund policy.
Why might mine look a little different from the photos?
Every Spinek is hand assembled in Lake Zurich, Illinois, so small imperfections are normal. Each one is tested and paired with a setup instructions link before it ships, so you know the chip works. Tap it when it arrives to see the instructions.
It isn't opening on my phone. What do I check?
Thick, metal or magnetic phone cases can block the tap, so try it with the case off and hold it on the back of the phone for a second. On Android, make sure NFC is switched on in settings. If you wrote your own link in an app like NFC Tools, paste only the link, starting with https://. Any text in front of it stops the link from opening.
How to connect
Point it wherever you want. Takes two minutes.
The chip inside is a rewritable NTAG213. You write it once with a free app, and you can rewrite it up to 100,000 times after that.
Only you ever need an app. The people who tap it just get your link.
1
Get the app — you, once
Download NFC Tools. It's free, it's on both the App Store and Google Play, and it's what you'll use to write your link onto the tag.
This is the only app involved anywhere, and only you need it. The people who tap your Spinek install nothing.
On Android, check NFC is switched on first: Settings → Connected devices → NFC. iPhone 7 and newer can write tags out of the box.
2
Find your phone's tap spot
NFC only reaches a couple of centimetres, and the antenna sits in a different place depending on the phone. Hold the Spinek flat against the back and slide it slowly until the phone buzzes.
A thick case, a popsocket, or a metal plate for a magnetic car mount will block the signal. If it's being stubborn, take the case off.
iPhoneTop of the back, beside the cameras. Same spot on every iPhone since the 7.AndroidUsually the middle or upper-middle of the back — but it moves around by model. Slide the Spinek slowly across until it buzzes.
3
Wipe whatever is on it
Open NFC Tools → Other → Erase tag, then hold the Spinek to the tap spot until it reads Erase successful.
You don't strictly have to — writing a new link overwrites the old one anyway. It's just a clean way to start, and it's how you blank a Spinek before passing it on to someone else.
4
Write your own link
Open NFC Tools → Write → Add a record, then pick what you want the tag to do:
URL / URI — any web link at all: LinkedIn, a Google review page, a Linktree, a YouTube or TikTok video, a Maps pin, a shared folder
Contact — drops your name and number straight into their phone
Text — plain words, no link
Phone number, email or SMS — starts the call or the message for them
Wi-Fi network (Android only) — guests join without you reading the password out loud
Paste your link in, hit Write, and hold the Spinek against the tap spot for two or three seconds until it says Write successful. Keep it still — moving it mid-write is the usual reason a write fails.
The chip holds 144 bytes, which works out to roughly 130 characters of link. Long tracking URLs won't fit — run them through a shortener first.
5
Test it, then forget about it
Lock your phone, wake the screen, and tap the Spinek against the spot you found. Your link should slide up as a notification.
iPhone XR and newer read tags on their own with no setup. iPhone 7, 8 and X need the NFC Tag Reader added first, under Settings → Control Center.
Changed your mind later? Just repeat step 4. These chips take somewhere around 100,000 rewrites, so you'll never reach the end of it.
If it doesn't work the first time
Nothing happens when I tap it+
Three usual causes: NFC is switched off (Android: Settings → Connected devices → NFC), you're on the wrong part of the back, or the case is too thick. Wake the screen first as well — most phones won't read a tag on a dark, locked screen.
It says the tag is read-only+
The tag has been locked. NFC Tools has a lock option under Other, and it is permanent — a locked tag can never be rewritten. Don't use it unless you are certain. If yours arrived locked, message us and we'll replace it.
The write keeps failing halfway through+
Hold still. The Spinek has to stay against the antenna for the full two or three seconds. Easiest fix: lay the phone flat on a table, rest the Spinek on the tap spot, and let go of it instead of holding both.
My link is too long to fit+
144 bytes is about 130 characters. Anything longer — long UTM tracking strings especially — needs a shortener first. The tag then points at the short link, which forwards wherever you want.
Can I put a video on it?+
A video, yes — as a link to one. A tag this size holds a link, not a file. Point it at the YouTube, TikTok, Vimeo or Drive URL and the video opens full screen when someone taps.
Does it work on an iPhone without an app?+
Yes. iPhone XR, XS and newer read NFC tags natively, with no app and nothing to enable. Android phones do too, as long as the phone has NFC and it is switched on in settings.
