iPhone users: This October Prime Day tracker deal means you'll never lose your wallet again

We're a forgetful bunch of people in my house; it's the sole reason we have a smart garage door opener and why "Have you seen my wallet" is one of the most uttered phrases at home. As iPhone users, we have several AirTags and take advantage of the Find My feature in AirPods and other devices, but the Eufy SmartTrack Card, which also works with the Find My network, has made the biggest difference, and it's only $17 on Amazon during October Prime Day.

This slim, 2.4 mm-thick card-shaped device fits your existing wallet as it's not a coin-shaped tracker like the AirTag, so there's no need to buy an extra wallet or holder to attach it to your wallet. You can share the SmartTrack location with others using the Eufy Security app, for others to help you find it when necessary or use it on their own, like a kid learning to keep tabs on their wallet.

The SmartTrack Card uses Bluetooth to track the items, and you can get alerts any time your item is left behind when you depart from a place, get directions to your wallet, and play a loud alarm on it to find it easily. It's only available for iOS as it only works with Apple Find My, so Android devices aren't supported.

The Eufy SmartTrack Card is water-resistant, and the battery lasts up to three years, as it's not replaceable or rechargeable. It comes with a metal clip, so you can clip it to the outside of your wallet to make it easier to hear and track, especially if you have RFID-protected wallets.
