Daniella can track the package she mailed to her brother using package tracking technology that relies primarily on scanning the code (such as a barcode or QR code) on the package at each stage of its journey. This scanning process updates the package's status and location in real time as it moves through the delivery system, allowing both sender and recipient to monitor its progress online or via mobile apps
. Key technologies enabling this tracking include:
- Barcode scanning: At various checkpoints, the package’s barcode is scanned, automatically updating its location and status in the carrier’s tracking system
- RFID (Radio Frequency Identification): Some shipments use RFID tags that can be read remotely to provide real-time location data and other environmental information about the package
- GPS integration: While GPS helps delivery vehicles navigate efficiently, the actual package tracking for customers is mostly based on scans at checkpoints rather than continuous GPS tracking of the package itself
Daniella can use the tracking number provided when she mailed the package to enter it on the carrier’s website or mobile app (such as USPS, FedEx, UPS, or other services) to see the current status, location, and estimated delivery date of her package
. In summary, the technology that enables Daniella to track her package is the system of scanning the package’s unique code at each leg of its journey, which updates the tracking information accessible online or via apps
