1.8 mm thick.
About two credit cards. It goes in the slot, not loose in the bag.
Find My tracking card
It lives in a card slot at 1.8 mm, and your iPhone says the wallet stayed behind while you are still at the door.

In the slot you never empty
An AirTag is about as thick as ten credit cards. That is why it ends up loose in a bag instead of in the wallet — and a tracker that is not on the thing you lose is not doing anything.
1.8 mm (seller-stated) — about two credit cards. It sits behind your bank card, in a passport holder, in a bag pocket, and you stop noticing it is there.
Drop it on any Qi or MagSafe pad for about two hours and it runs up to five months (seller-stated). No sealed battery, no card to throw away when it runs flat.
Find My pings your iPhone when the wallet stays behind and you walk off. That alert is part of Find My — there is nothing extra to subscribe to.
The card, up close
Why choose it
At 1.8 mm it goes behind a bank card and stays there. That is the whole reason it works: the tracker is on the wallet every day, not in the drawer where you left it.
Recharge it. Keep it.
Find My notifies your iPhone when you walk away from the wallet. Tile puts that same alert behind a $2.99 monthly plan; here it comes with the phone you already own.
Two hours on a pad, then months of carrying it. Cards with sealed batteries last one to two years and then the whole card is finished.
IP68, seller-stated.
You pat the pocket and it is not there.
Ten seconds of cold panic, then the mental replay.
The card in the wallet skips all of that.
Your phone already told you, at the door.
Pick the right one
Three different trade-offs. If you are on Android, the third column is your column — the first two will not pair with your phone at all.

Plain terms
It joins Apple Find My, the same network that locates an AirTag. Nearby it rings and shows on the map straight away. Away from you, its position updates whenever any Apple device passes close by — in a town or a city that happens constantly.
Somewhere with no Apple devices around, there is nothing to relay the position, and the map holds the last place it was seen. It needs an iPhone or iPad: Find My is an Apple system, and there is no Android app for this card.

I’m the type who can’t leave a coffee shop without leaving SOMETHING behind and my wallet was the usual victim but now my phone literally yells at me before i get to the door. Tagsley is so thin i literally forget it’s there but it’s saved me twice this month already lmao
Miranda
I fly almost every week for work and checked bags are a gamble…. This card is such a brilliant investment cuz it lets me see exactly where mine is whether it’s in the belly of the plane or still on the tarmac. Best item tracker I’ve ever had!
Maynard
I tried an Tagsley in my wallet but it was like sitting on a pebble while this card just slides in like another card and works seamlessly with my phone’s Find My app and max bonus points for wireless charging. It’s basically the tracker Apple forgot to make lolol

Before you buy
No. The card runs on Apple Find My, so it needs an iPhone or iPad. On Android it will not pair at all — a Tile or a Chipolo card is the right buy there.
No card this thin carries GPS. It locates through Find My: nearby it rings and shows on the map, and further away its position refreshes each time an Apple device passes close to it. In built-up areas that is near-constant; somewhere empty, the map holds the last place it was seen.
You charge it. Two hours on any Qi or MagSafe pad gives up to five months (seller-stated). Cards with a sealed battery last one to two years and then the card itself is finished — this one is not built that way.
No. It is added in the Find My app that is already on your iPhone, the same way an AirTag is. There is no separate app and no account to create.
None. Left-behind alerts, the map and the ring are all part of Find My, which comes with the phone. Nothing here sits behind a premium plan.
It is IP68 rated (seller-stated) — spills, rain and pocket damp are within scope.
It is a standard credit-card footprint at 1.8 mm, so any card slot takes it. In a tight minimalist wallet it uses the space of about two cards.
