The Samsung Galaxy SmartTag 2 radio tag uses Bluetooth LE (Low Energy) to transmit data. The device operates without a GPS module, SIM card, or Wi-Fi, relying on nearby Samsung smartphones to relay its location to the cloud. The tag scans the Bluetooth ether every 5 to 60 minutes, as configured, within a radius of 100-120 meters in direct line of sight.
A third-party Android application called uTag, available on GitHub, allows non-Samsung Android devices to manage these tags. By patching the stock SmartThings app, uTag enables users to register a free Samsung account and pair the device. This bypasses the ecosystem restrictions typically associated with Samsung's proprietary network.
The tag is priced at approximately 1,700 ₽ in Russia. It is powered by a single CR2032 battery, which provides approximately one year of operation. The system is designed for urban environments where the density of Samsung devices is high, making it a viable tool for tracking luggage, vehicles, and pets.
