Comparable in size to a credit card, Verbatim's My Finder Bluetooth Card easily slips into your wallet, attaches to the back of your phone, or can be used as your luggage tag. This card tracking device works exclusively with Apple's Find My App to locate your lost items. When you are in close range of the Apple Find My ecosystem, you can locate your lost item by selecting "Play Sound" in the app, which allows you to follow the beep to your item. You can also select your item in the app and track it on the map - an anonymous, encrypted process to protect your privacy. Another app feature, Lost Mode, allows you to enter your contact details so others in the Apple Find My network can assist in locating your missing items. Easy to charge, the My Finder Bluetooth Card also features a circular design with a built-in magnetic charging surface. Simply align the My Finder Card with the wireless charging pad and it will snap into place, initiating the charging process automatically. Verbatim's My Finder Bluetooth Card is water-resistant, dustproof, and has a 2-year limited warranty.
