eufy SmartTrack Card E30 is a rechargeable Bluetooth item tracker designed to fit in a wallet. It works with the Apple Find My app and network—available on iOS only; it is not compatible with Android devices.
E30 measures 85 × 54 × 2.6 mm—the same width and height as a standard credit card—and weighs very little, making it flat enough to slip into any card slot. It connects via Bluetooth with a range of up to 260 ft (80 m) and relies on Apple's Find My network to locate items beyond Bluetooth range using nearby Apple devices.
The built-in battery is rechargeable via the included magnetic USB-C adapter and lasts up to 1 year per charge—no coin-cell battery replacements needed. The card is water-resistant for everyday use in rain.
E30 features an 80 dB built-in alarm, instant left-behind alerts from the Find My app (no subscription required for core tracking), shareable item location, a secure QR code that lets anyone who finds the item contact the owner, and a double-tap phone-finder feature that rings your phone even when it is in silent mode.
SmartTrack Card E30 is designed for wallets, passport holders, laptop bags, and folders. It is not a GPS tracker and does not work independently of Apple's Bluetooth and Find My network.

People Who Don't Want Battery Replacements: The rechargeable battery lasts up to 1 year per charge via the included magnetic USB-C adapter—no coin-cell batteries to buy or swap.
Core Tracking with No Monthly Subscription: Left-behind alerts and Find My location tracking require no paid plan; the eufy Security app also supports shareable location at no additional cost.

2. Not Ideal for
Android Users: SmartTrack Card E30 uses Apple Find My and is iOS only; it does not work with Android phones.
Long-Range GPSTracking: E30 uses Bluetooth and Apple's Find My network; it has no built-in GPS and cannot report live location independently of nearby Apple devices.

Shared Family Tracking with Non-iPhone Users: Find My location sharing is limited to Apple device users.
1. What is the difference between SmartTrack Card E30 and SmartTrack Card?
The main difference is the battery. SmartTrack Card E30 has a rechargeable built-in battery (up to 1 year per charge, charged via magnetic USB-C adapter). SmartTrack Card (non-E30) has a non-replaceable, non-rechargeable built-in battery rated for up to 3 years—it cannot be recharged and must be discarded when the battery dies. Both are credit-card size, iOS-only, and work with Apple Find My. Choose E30 if you prefer recharging; choose the standard SmartTrack Card if you prefer fewer charging steps over a longer lifespan.
2. Does SmartTrack Card E30 require a subscription?
No monthly subscription is required for core SmartTrack Card E30 features—including Find My location tracking, left-behind alerts, and alarm triggering. The eufy Security app is free. Location sharing with friends and family is also free.
3. Does SmartTrack Card E30 work with Android?
No. SmartTrack Card E30 is iOS only. It works exclusively with Apple devices via the Find My app and Bluetooth. It is not compatible with Android phones or devices.
4. Is SmartTrack Card E30 good for tracking a passport or luggage when traveling?
Yes. SmartTrack Card E30 is credit card-sized (85 × 54 × 2.6 mm) and 2.6 mm thin, so it slides directly into passport holders, travel wallet slots, and luggage pockets without adding bulk. It's water-resistant for use in any weather. When traveling internationally, it uses the Apple Find My network to report its location via nearby Apple devices in airports, hotels, and cities worldwide. Left-behind alerts notify you when you walk too far from your bag or passport case.
5. How does SmartTrack Card E30 track items beyond Bluetooth range?
When SmartTrack Card E30 is outside your Bluetooth range (up to 260 ft / 80 m), it uses the Apple Find My network, which includes hundreds of millions of Apple devices worldwide. Nearby Apple devices anonymously detect your E30's Bluetooth signal and securely report its location to your Find My app. The process is encrypted and private; other users cannot see your tracker or your data.
6. Can I use SmartTrack Card E30 to find my phone?
Yes. Double-tap SmartTrack Card E30 to make your iPhone ring—even if your phone is set to silent mode.
7. What happens if someone finds my lost item with E30 inside?
Anyone who finds your lost item can scan the QR code on SmartTrack Card E30 using any smartphone (Apple or Android). The QR code links to a secure page showing your preferred contact method—such as a phone number or email—so the finder can reach you to return the item. No personal information is stored on the card itself.
8. How do I charge SmartTrack Card E30?
Charge SmartTrack Card E30 using the included magnetic charging adapter and USB-C cable (a wall adapter is not included—use any standard USB-A or USB-C wall adapter). Attach the magnetic adapter to the card, connect the USB-C cable, and plug it into a charger. Battery status indicators: flashing blue = charging; steady blue = fully charged; red light when pressing the button = battery empty. A full charge supports up to 1 year of use.
9. How does SmartTrack Card E30 use the Apple Find My network?
SmartTrack Card E30 uses Bluetooth to connect to your iPhone within up to 260 ft (80 m). When your item is out of Bluetooth range, the card is detected by nearby Apple devices via the Find My network, which anonymously and securely reports its location to your Find My app. This means your E30 can be found anywhere there are Apple users nearby—at airports, shopping centers, hotels, and more. The entire process is encrypted; other users cannot identify your tracker or see your location.
10. How do I set up SmartTrack Card E30 in the Apple Find My app?
Press the button on SmartTrack Card E30 for 3 seconds until you hear a tone. Open the Find My app → tap Items → tap "+" → tap Add Other Item. The app will detect your E30. Follow the on-screen instructions to complete setup and optionally name your item (e.g., "My Wallet"). Setup takes under 2 minutes. Note: Your iPhone must be nearby, and Bluetooth must be enabled.
11. Does SmartTrack Card E30 have GPS?
No. SmartTrack Card E30 does not have GPS. It uses Bluetooth for close-range tracking (up to 260 ft / 80 m) and relies on the Apple Find My network for long-range location updates via nearby Apple devices. This means it cannot report real-time live location independently of Apple devices—if there are no Apple users nearby, the last known location is shown.
12. Can Android users use SmartTrack Card E30?
No. SmartTrack Card E30 is not compatible with Android devices. It requires an iPhone or other Apple device running the Find My app.
13. Does SmartTrack Card E30 support wireless charging?
