Another year, another step toward never losing anything ever again. At CES 2026, Anker’s smart home brand Eufy has just unveiled the successor to its popular wallet-friendly tracker: the eufy SmartTrack Card E40. This sleek, new accessory promises to build on the foundation of the older E30 model (which you can still find on sale for around $16.88) with some key upgrades that finally bridge the gap between iPhone and Android users.
For anyone who has ever frantically patted down their pockets or dumped out a bag searching for a missing wallet, passport, or suitcase keys, these slim trackers have been a minor miracle. The new E40 looks to make that miracle a little more powerful and a lot more inclusive.
What’s New in the E40?
The core mission remains the same. The eufy SmartTrack Card E40 is designed to slip discreetly into your wallet, passport sleeve, or luggage tag pocket. When the item goes missing, you have two main lines of defense.
First, you can ring a built-in, 100-decibel alarm from your smartphone app—a piercing sound that can help locate a wallet buried between couch cushions or in a jacket pocket.
The second, and most significant upgrade, is in the global tracking networks. The previous E30 model worked exclusively with Apple’s Find My network, leveraging hundreds of millions of Apple devices worldwide to pinpoint a lost item's location. The new E40 adds compatibility with Android’s Find Hub network, finally extending that same crowd-sourced tracking power to the Android ecosystem. This is a major leap forward, meaning your tracker can be located virtually anywhere on the planet, regardless of which smartphone platform you or the person walking past your lost item uses.
Sleeker Design, Smarter Features
Eufy has also shaved things down a bit. The company claims the E40 is thinner than its predecessor, coming in at a credit-card-friendly 1.7 mm thick (about 0.067 inches). It charges wirelessly, and a single charge is touted to deliver an impressive five months of battery life, minimizing maintenance hassle.
Connection is handled via Bluetooth 5.1, and Eufy also mentions the card will offer a phone-finding function. This essentially works in reverse: by pressing a button on the card, you can make your paired smartphone ring, ideal for when your phone has slipped under a pile of papers.
For those ready to upgrade or jump into the tracking game, the eufy SmartTrack Card E40 is available for pre-order or purchase on Amazon through our affiliate link below. This is a great way to secure the latest model and see current pricing.
Price and Release Date
Anker plans to release the eufy SmartTrack Card E40 in the United States sometime in the first quarter of 2026, with a target launch before the end of March. The official retail price is set at $34.99. For comparison, the E30 launched at $29.99 back in early 2023, positioning the E40 as a modest price increase for its cross-platform capabilities and refined design.
The Bottom Line
The eufy SmartTrack Card E40 shapes up to be a thoughtful evolution of the wallet tracker. By embracing both Apple Find My and Android Find Hub, it solves the biggest limitation of its predecessor and many competitors. When combined with its slim profile and long battery life, it becomes a compelling, platform-agnostic solution for keeping tabs on your most important everyday items. If you’ve been waiting for a tracker that works seamlessly whether you’re on Team iPhone or Team Android, your wait is almost over.
