eufy Security SmartTrack Card T87B2 Product Manual

Introduction: eufy Security SmartTrack Card T87B2 overview

The eufy Security SmartTrack Card T87B2 is a slim, credit-card-sized Bluetooth tracker designed to help you keep tabs on everyday essentials such as wallets, passports, luggage tags, and document holders. It works with Apple Find My, letting you locate compatible items through the Find My app and the broader Apple device network, while also offering eufy app features such as left-behind alerts and item sharing. The card includes an ultra-loud alarm, is water-resistant, and has a built-in battery rated for up to 3 years, making it a practical low-maintenance tracking solution for iPhone users.

This tracker is especially useful for commuters, travelers, students, and anyone who routinely misplaces small valuables. A notable convenience feature is reverse finding: you can use the card to help locate your phone by triggering a sound from the paired device. The unit is designed to stay discreet in a wallet without adding bulk, and its thin profile is one of its main selling points compared with bulkier key-fob style trackers.

Estimated pricing is around the low-cost consumer tracker range, with one listed price at about R440 and another retail listing around $29.99, depending on region and seller availability. Availability appears strongest through eufy’s own store and major online retailers, but regional stock can vary.

Compared with a typical AirTag-style tracker, the SmartTrack Card is flatter and easier to slip into a wallet, but it is more specialized for flat-item tracking rather than keychain use. Against similar card trackers, its strongest advantages are Apple Find My support, a long battery life, and the ability to help locate your iPhone.

Setup guide: how to pair and use the SmartTrack Card

Before setup, make sure you have an iPhone or iPad signed in to Apple ID and running the Find My app. Press and hold the button on the SmartTrack Card for about 3 seconds until you hear a tone, then open Find My and tap Items > + > Add Other Item. Follow the on-screen prompts to complete pairing.

After pairing, place the card in a wallet or slim compartment where the button is not constantly pressed. Configure options in the Find My app, such as notifications for when the item is left behind, Lost Mode, and shared access if you want family members to view the item location. You can also use the eufy Security app for additional device management features, depending on your region and app version.

Troubleshooting tip: If the card is not discovered, confirm Bluetooth is enabled, the phone is nearby, and the card has not been accidentally held down by tight wallet compression. Safety note: do not attempt to open, recharge, puncture, or replace the battery, because the T87B2 uses a sealed, non-serviceable battery design.

Troubleshooting: common problems and fixes

Not pairing: Restart Bluetooth on your iPhone, keep the card close to the phone, and re-press the button until you hear the tone.
No sound from the tracker: Increase volume in the Find My app and verify that the card is not physically muffled by thick materials.
Wallet button activation: If the card is triggering unexpectedly, inspect the wallet fit; compression can press the button continuously in tight slots.
Battery depletion: Because the battery is sealed and non-replaceable, a dead unit must be replaced rather than repaired.
Compatibility issue: Android phones are not supported for Find My setup.

There are no user-facing error codes documented in the available product support material, so most issues are handled through connection checks, app re-pairing, or device replacement. To prevent problems, keep the card away from extreme pressure, avoid moisture exposure beyond normal water resistance, and maintain updated iOS and Find My settings. Warranty, returns, and lifetime support are offered through eufy’s support channels, with a 30-day money-back guarantee listed for some retail regions. For help, use the eufy Support Center and product manual resources.

Customer reviews: real-world feedback on the SmartTrack Card

Common customer praise centers on the slim profile, easy wallet fit, and simple Apple Find My integration. Many users describe it as a strong 4.3/5-style product for daily carry because it disappears into a wallet while still offering useful tracking and phone-finding features. Users also appreciate the long battery life and loud alert sound.

Common complaints focus on the lack of Android compatibility, the sealed battery, and occasional accidental presses when stored in a tight wallet. For buyers who use iPhone and want a low-profile tracker for a wallet or passport holder, it is an easy recommendation. For users who need rechargeable hardware or universal compatibility, a different tracker may be the better choice.
