First off, it's a palm-sized tag that has a loop built into the polymer, and it comes with a strong and secure metal clip for attaching it to your keys or luggage. No additional bits to buy, like you have to with the AirTag. Also, the loop is tough enough to survive day to day use without breaking off. Inside the tag is a super-loud, ear-splitting 130 dB beeper that is far superior to the puny 80 dB beeper in the AirTag.
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.
Unlike an AirTag, this SwitchBot tracker boasts up to three years of battery life. Instead of a CR2032 replaceable coin battery, the SwitchBot Wallet Tracker Card's battery can't be replaced or recharged, so you'd have to toss it after it dies.
