QCard is a hexagonal plastic, durable card designed for efficient and accurate student response recording. Each of its six vertices is labeled with options A through F, allowing students to select their answer by orienting the card accordingly. At the center of the QCard is a black-and-white square code, similar to a QR code, which serves a dual purpose: it uniquely identifies the student and encodes the selected answer.

This design enables quick scanning and automated grading, making QCard a valuable tool for classrooms, assessments, and interactive learning environments. It ensures accuracy, durability, and ease of use, reducing reliance on traditional answer sheets while enhancing digital integration in education.
