ABSTRACT:
A Radio Frequency Identification (RFID) Card Reader is a cost-effective device used to read passive RFID tags from a distance of up to 2 inches. RFID technology is widely used in access control systems, automatic identification, inventory management, robotics, payment systems, vehicle security, and parcel tracking applications. The RFID reader detects the unique identification number stored in an RFID tag and transmits the data through serial communication at a baud rate of 9600 bps, allowing it to interface easily with a microcontroller or computer.
In the RFID – Based Parcel Tracing System, every parcel is attached to an RFID tag containing a unique identification number. As the parcel moves through different postal departments or distribution centers before reaching its destination, each center is equipped with an RFID reader. Whenever the parcel passes through a center, the RFID reader automatically scans the tag and sends the unique identification number to the microcontroller.
The microcontroller processes the received data and displays the parcel’s unique ID along with its current location on a 16×2 LCD display. This enables postal staff to monitor the parcel’s movement at every stage of the delivery process. Customers can also track the parcel’s status based on the information recorded at each scanning point.
To improve system security, the project can detect unauthorized or invalid RFID tags. If an unauthorized tag is detected, the system generates a long beep using a buzzer to alert the operator and prevent unauthorized access or incorrect parcel processing.
The hardware includes a 7805 voltage regulator, which provides a stable 5V power supply and minimizes noise and voltage fluctuations. The RFID reader communicates with the microcontroller through the serial communication interface and typically operates at 9600 bps or 4800 bps. A 16×2 LCD is connected to the microcontroller through digital I/O pins to display the parcel identification number and its current location, making the system simple, reliable, and suitable for real-time parcel tracking applications.
