Xiaomi has entered the market for Bluetooth-based object tracking devices with the release of its Xiaomi Tags, offering a much lower price than competing products like Apple AirTags and Samsung SmartTag 2. A single Xiaomi Tag costs 14.99 €, and a set of four is available for 49.99 €. In comparison, Apple AirTags cost 35 € for one and 119 € for a set of four, while Samsung SmartTag 2 devices are priced at 39.99 € for one and 129.90 € for four. The Xiaomi Tag has a rectangular shape, measuring 46.5 x 31 x 7.2 mm and weighing about 10 grams. This makes it smaller and lighter than the Samsung SmartTag 2 and different from the round Apple AirTags, which have a diameter of 31.9 mm. The Xiaomi Tag also includes a built-in arch for easy attachment to a keychain, unlike Apple AirTags, which require an extra case. The Xiaomi Tag uses a CR2032 battery, which provides about one year of use. It supports Bluetooth BLE 5.4 and NFC, but does not include UWB (Ultra Wide Band) technology, which allows for highly precise short-range tracking. The lack of UWB helps keep the price low but limits the accuracy of location tracking compared to devices with this feature. The Xiaomi Tag includes a piezoelectric buzzer that can be manually activated to emit a sound, helping users find the device more easily. The Xiaomi Tag has an IP67 water resistance rating, meaning it can be submerged in fresh water for 30 minutes as long as the temperature difference between the water and the device does not exceed 5 degrees Celsius. This condition might not be common in everyday use, but it still provides a reasonable level of protection against water damage. The Xiaomi Tag supports both Google Find My and Apple Find My services, allowing users to choose between Android and iOS systems. However, it can only use one of these networks at a time. If set up on an iPhone, it will use Apple Find My, and if set up on an Android device, it will use Google Find My. There is no dedicated app for the Xiaomi Tag; instead, users must manage it through either Google Find My or Apple Find My, which are similar in functionality. Users can name the Xiaomi Tag, update its firmware, and activate a "Lost mode" through these apps. The proximity search feature allows the tag to emit a sound to help locate it, but without UWB, the tracking precision is limited. The Android app shows a wavy circle that fills as the user gets closer, while the Apple Find My app includes additional features like "Notify me if forgotten." The Xiaomi Tag is praised for its affordability, compatibility with both Android and iOS, ease of use, and practical design. However, the lack of UWB technology and the need to choose between Google and Apple ecosystems are considered notable drawbacks.
