The eufy Security SmartTrack Card E30 is a ultra-slim Bluetooth item tracker that integrates with Apple Find My on iOS devices. At just 2.4mm thick, it's designed for wallets and slim pouches rather than bulky keychains.
Key specs: Bluetooth-only connectivity (no UWB), non-replaceable sealed battery rated for up to 3 years, water-resistant coating, and an ultra-loud alarm despite its card form factor. Uses Apple's Find My network for crowd-sourced finding across iOS devices. Includes a metal clip attachment.
Ecosystem: iOS only—Android devices are not supported, making it exclusively for iPhone/iPad users. Features free left-behind alerts and can trigger your phone's ringer even in silent mode.
Who it's for: iPhone users seeking a thin card-format tracker for wallets and flat pouches who value the long battery life and premium build quality over cross-platform compatibility or precision finding.
