10 reasons people are swapping their AirTags for a card

A tracker only works if you actually carry it. That one sentence explains most of this list.

1

It actually fits in your wallet

A round tracker is about eight millimetres thick. Your wallet notices. Rhinokey is 1.8 mm and the size of a bank card, so it slides into the slot you were not using anyway and the wallet still closes flat.

2

It works on Android too

Apple trackers are built for iPhones. Rhinokey works with Apple Find My on iPhone and iPad, or with Google Find Hub on Android. You pick your system when you order, so the Android half of your family is not left out.

3

There is no battery to replace

Coin-cell trackers ask for a fresh battery roughly once a year, and always at the worst moment. Rhinokey charges wirelessly: lay it on a pad, walk away, done. Nothing to buy, nothing to throw away.

4

Nobody can tell it is there

It has a chip and a contactless mark, so in a wallet full of bank cards it reads as one more bank card. A keyring disc announces itself. This does not.

5

Your passport finally has a tracker

A passport holder has no keyring loop and no room for a disc. A card slides straight in next to the passport, which is exactly where you want it on the day you cannot find it.

6

One card, a hundred places

Wallet, suitcase, camera bag, laptop sleeve, glove compartment, toolbox, the bag your kid takes to practice. Anything with a pocket or a sleeve takes a card. That is the whole point of the shape.

7

You set it up in seconds

There is no Rhinokey app. You open the app that is already on your phone, hold the card near it and give it a name. Most people are finished before the kettle boils.

8

You can ring it until you find it

When it is nearby, you make it play a sound from the same app and follow the noise. When it is not, the Find My or Find Hub network shows you where it was last seen, anywhere those phones are.

9

No subscription. Not now, not ever

You pay once. There is no account to create, no monthly fee and no premium tier that unlocks the feature you actually wanted. The card you buy today keeps doing its job.

10

The part nobody adds up

A tracker is rarely one purchase. Count the replacement batteries over a few years, and count the one you buy again because the first was too bulky to carry. Then count ours: the card, and a charger you already own or buy once.
