I'm an iPhone user, and so I've stuck onto pretty much everything of value (using the excellent accessories that makes for that task). My trail buddy is an Android user, and they're having to use something different. Also: I found an AirTag alternative that beats the Bluetooth tracker in meaningful ways (including price) While keys and backpacks are protected using the new , they're a bit on the big side to go into a wallet.
The Card 5 looks and feels slightly thicker than a normal credit card. I've had credit-card-sized tracker tags in the past, and at only 0.07 inches/1.74 mm thin, this tag is significantly thinner than those -- some 30% thinner, according to Pebblebee. Inside the tough, durable exterior -- designed to IPX6 standards to shrug off dust and rain -- is a lot of cool electronics.
