Smart Tag is a battery powered Bluetooth Low Energy (BLE) enabled wireless sensor device. The Smart Tag monitors Cold Drink Equipment (CDE) Temperature, Light, door open/close, and Movement and retains these in its internal memory for later retrieval. SmartTag is easy to install in a cooler and can be installed in less than 5 minutes. Any BLE/ iBeacon enabled mobile application can detect all Smart Tag enabled CDE’s in a 50 feet radius. The Smart Hub, Smart Core or Virtual Hub can collect this data on proximity and upload to our cloud platform for processing.
