GoKawiilPeak Design Beacon Finder Card for $40: At just 1.8 millimeters thick, this is one of the slimmest wallet trackers I’ve tested. It slid into my card holder without adding noticeable bulk, which is more than I can say for every tracker card. It’s also IP68 rated for dust and water resistance, making it one of the more durable cards. Setup took only a few seconds after its initial charge, and the rechargeable battery lasts about five months between charges. Unfortunately, it only works with Apple’s Find My network, so it’s not for Android users. If you own an Android, I’d recommend the Chipolo Card or the UAG Metropolis Dual Tracker Card instead.

Groove Smart Wallet Trace for $125: According to the company, the Groove Wallet is the first wallet with built-in Find My capabilities and a built-in battery. It blocks RFID transmission—although I feel obligated to remind you that there has never been a real-world case of RFID skimming—and is made from attractive aerospace-grade anodized aluminum. It fits up to six cards, which you can push out easily with a flick of the thumb. There's also a money clip on the back for your cash. I don't particularly like a hard wallet; it doesn't conform to your body, so it's uncomfortable to have it clank around in your pocket. It also doesn't have a zipper, so you can't stuff random receipts inside. Still, it's much more protective than a leather wallet. It's also only compatible with iOS, not Android. It has a 94-year warranty but a battery life of around two years, after which you need to contact Groove customer service for a $10 replacement. —Adrienne So
Life360 Tile Sticker for $25: Even as AirTags and other Bluetooth finders have become more popular, Tile trackers remain ubiquitous and come in a wider variety of forms. The latest models are even more durable and waterproof, and the batteries are replaceable. However, I still think the most useful form is the Tile stickers, which are great for remotes and the back of my Kindle Paperwhite. Each sticker is waterproof, has a three-year battery life, and offers a 150-foot range, which is pretty impressive for a tool so small. After a year, the small bump did get knocked off my much-abused Kindle; however, I still think this is a fair price to pay for being able to read my requisite soothing 10 to 15 pages of Naomi Novik before going to bed every night. —Adrienne So
