SwitchBot
This wallet specialist doubles as a SwitchBot lock key and automation trigger while using Apple Find My. The IP67 card lasts a claimed three years, but its sealed battery ends tracking life.
$23 typical
Unlike a bare wallet tracker, it combines Apple Find My, IP67, a three-year battery, two-way phone finding, NFC card-key capability and SwitchBot automation. The price is driven by that functional integration, not logo value.
A durable engineering plastic appropriate to a thin, repeatedly flexed wallet card.
Delivers a long claimed three-year service life, but cannot be replaced.
An unusually well-resolved card object: thin enough for a wallet, physical button for reciprocal finding, and genuinely useful NFC/automation behavior. The trade-off is a sealed cell.
The sealed 540 mAh battery is rated for up to three years; that is convenient but a real serviceability limitation. The card can continue as an NFC card after tracking power is exhausted.
