TL;DR

• Eufy has launched the SmartTrack Card E40 tracker.
• This tracker has a 100-decibel alarm and supports Apple and Google’s Find networks.
• Expect to pay $34.99 for the SmartTrack Card E40 when it goes on sale in Q1 2026.

Wireless trackers are very popular today, especially in the wake of Apple’s Find My Network and Google’s Find Hub. Now, eufy has launched a brand-new tracking card that supports Apple and Google’s wireless networks.

The Eufy SmartTrack Card E40 is a card-sized tracker measuring 1.7mm thick, which means it should fit into your wallet just fine. The tracker indeed supports both Google and Apple’s Find networks. That’s a welcome change from the brand’s previous card, which only supported Apple’s network. Eufy also promises five months of battery life on a single charge.

This is all well and good so far, but the card is also equipped with an ultra-loud 100-decibel siren alarm. Needless to say, you should be able to hear this tracker just fine in most situations.

Eufy says the SmartTrack Card E40 will go on sale in Q1 2026 for $34.99. So it’s definitely worth a look if you’re in the market for a larger tracker with a suitably ear-piercing alarm. We’re just glad Eufy is finally launching trackers with Find Hub support after a delay of more than a year.
