The ZIKE SmartCard has an ultra-thin design, less than 2mm thick, which corresponds to a credit card. It can be easily put into a wallet or hung on a keychain. The ZIKE smart air tag card is IPX7 waterproof and comes with a built-in battery. On a single charge, it lasts up to half a year and can be charged wirelessly. The ZIKE ZIKE Wallet Tracker supports the Apple Find My network. You don’t need to install an APP to find lost items directly on your iPhone, iPad, or Mac. It can solve the problems of forgetting where to put your keys, wallet, or schoolbag in daily life, finding your car in a complex parking lot, and even locating lost children and the elderly.
