Technologies used in Tracking Products
Tracking devices are becoming increasingly popular as the world becomes more connected and the need for real-time location tracking and monitoring increases. There are various types of tracking devices, including GPS trackers, RFID tags, and Bluetooth trackers. GPS trackers are devices that use the Global Positioning System (GPS) to determine their location and transmit that information to a central server. They are commonly used in fleet management, personal tracking, and asset tracking applications.
RFID tags, on the other hand, are small electronic devices that can be attached to objects, animals, or people to track their movement. RFID technology uses radio waves to transmit data, which is then collected by a reader device.
1. Barcodes
