False. Devices such as computers and credit-card readers are based on scientific principles in fields such as physics, mathematics, and engineering. These devices utilize scientific knowledge and technology to function effectively and efficiently.
This statement is inaccurate; computers and credit-card readers are fundamentally based on scientific principles, particularly in fields like computer science, electrical engineering, and information theory. Computers operate using binary logic and complex algorithms developed through scientific research. Similarly, credit-card readers utilize principles of electromagnetism and data encoding to process transactions securely. Thus, both devices are rooted deeply in scientific understanding and technological advancement.
