UGREEN iOS Smart Finder Tracker FMN Anti-lost Device Card-type Lithium Rechargeable FMN certified for Apple 12 Months Life Black

Accuracy:not tested yet but seems to pair ok and give locations. \nBattery life: the claimed battery life is 12 months. It is charged with a custom usb cable, not wirelessly like some other card style tags.\nCompatibility: As this is an item / tag, it’s isn’t possible to track it with an Android device or via the iCloud findme website. The web site only works with devices like iPhone/ iPad/ MacBook. But as long as you have at least one Apple device you can use it to track. It’s is the size of a credit card, but slightly thicker, so good for wallets or documents. See photo for charging device, usb A to custom connection.
