The tracker that finally fits inside your wallet

Coin tags are great on keys. But for your wallet, passport and luggage, a credit-card-thin tracker is the one that actually disappears into your stuff.

You're at the register, the line behind you is growing, and your hand pats an empty back pocket. Then the other pocket. Then the jacket.

Your stomach drops before your brain catches up. Or it's the airport carousel, and every black suitcase looks like yours until it isn't.

Most of the time the wallet turns up on the car seat and the bag comes out last. But those ten minutes of panic are exactly why so many people now carry a tracker. The question is which kind actually fits the things you're most afraid to lose.

The short version: if the thing you worry about most is your wallet or passport, a card-shaped tracker is the type that slips in without a bulge.
The card we looked at

Our take

Pros and cons

What we like

  • About 1.7 mm thin, fits a wallet card slot
  • Works with iPhone and Android finding apps
  • Rechargeable, about 6 months per charge
  • Left-behind alerts and a built-in sound
  • No monthly fees or subscription
  • 60-day return policy

Keep in mind

  • Location updates through nearby phones, so remote areas may update less often
  • Needs a recharge roughly twice a year
  • Water resistant, not waterproof
  • Designed for your own belongings. Never use any tracker to follow a person without their consent
