Anker Japan released the Eufy SmartTrack Card E40, a credit card-sized item tracker, on May 27, 2026 under its smart home brand Eufy[1]. It is the first Eufy tracker compatible with both Apple's Find My and Google's Find Hub, and serves as the flagship of the Eufy SmartTrack lineup. The body is about 1.7mm thick, roughly 30 percent slimmer than the previous model, and supports wireless charging[1]. The price is 5,990 yen including tax[1].
The First Eufy Tracker to Support Both iOS and Android
The SmartTrack Card E40 is the first Eufy tracker to work with both Apple Find My and Google's Find Hub[1]. Users can check the card's location through the Find My app on iPhone, iPad, and Mac, or through Android's Find Hub network on Android devices.
The key benefit is continuity. Users do not need to buy a new tracker when they switch between iOS and Android, since the same card can be re-registered to either ecosystem[1]. Anker Japan notes, however, that the card cannot be located through Apple Find My and Find Hub at the same time — it has to be registered on one platform at any given moment[1].
Anker Japan adds that the SmartTrack series has sold more than one million units cumulatively in Japan since its October 2022 debut, and that the E40 inherits that lineage as the latest generation[1].
Around 1.7mm Thin with Wireless Charging Support
The card is designed to slip into wallets and pass cases. At about 1.7mm, it is roughly 30 percent thinner than the original Eufy SmartTrack Card[1]. The slim profile makes it easy to fit into a card slot in a wallet, a card case, a passport holder, or even the inner pocket of a small bag[1].
Power is handled through wireless charging[1]. A pad-style wireless charger can top up the card, and Anker Japan states that a single charge lasts up to five months, with the caveat that actual battery life depends on the usage environment[1]. Because there is no coin battery to replace, long-term use does not generate extra disposable batteries.
An 80dB Alarm and a Lost Mode Powered by a QR Code
The search experience has been upgraded as well. From the Eufy app, users can trigger an approximately 80dB alarm on the card to help pinpoint where it is[1]. The volume is loud enough to be heard even when the card is buried in a bag or tucked away in a room.
For cases where the item ends up in someone else's hands, the card includes a lost mode. Once lost mode is enabled in the app, the QR code printed on the back of the card becomes active, and a person who scans it with a smartphone can see the registered owner's contact information[1]. The contact details are only shown while lost mode is on, so day-to-day privacy is protected[1].
The card also supports left-behind alerts and bulk management when multiple cards are used together — convenient for users who want to keep one card in a wallet, another in a bag, and another in a passport holder[1].
Pricing and Availability
The price is 5,990 yen including tax[1]. Distribution channels include the Anker Japan official online store's Eufy SmartTrack landing page[2], the directly operated Anker Store, Amazon.co.jp[3], Rakuten Ichiba, and select consumer electronics retailers[1]. Amazon.co.jp has been carrying the product from launch day, making it straightforward for shoppers to compare the SmartTrack Card E40 with existing trackers such as Apple AirTag and Samsung Galaxy SmartTag.
Summary
The Eufy SmartTrack Card E40 combines an approximately 1.7mm slim body, wireless charging, up to five months of battery life on a single charge, an 80dB alarm, and a QR-based lost mode — and it is the first Eufy tracker to ride both the Apple Find My and Find Hub networks. For users who have been juggling separate trackers for iOS and Android, or for households where both platforms coexist, the card offers a flexible single device that does not need to be replaced when the user changes phones.
