The Eufy Security SmartTrack Card is a great, cheaper alternative to AirTags.
Right now, you might get a SmartTrack Card for$16.98(originally $29.99).
This is the lowest price I have seen for this product after checkingprice-checking tools.
you could choose to find your belongings via Bluetooth or remotely via Apple’s Find My data pipe.
If you decide to use Bluetooth, you will need the Eufy Security app.
