Ever scanned a QR code that was scratched, faded, or partly covered and wondered how it still worked? 📱 QR codes use built-in error correction that can help recover missing information, allowing the code to remain readable even when part of it is damaged. It is a smart example of how technology is designed to solve real-world problems before they happen. #iCodeSchool #STEMForKids #TechnologyForKids #CodingForKids #TechFacts
