This course teaches QR codes as scannable data carriers—not as a marketing analytics platform. You will learn what gets encoded, how error correction works, common payload formats (URLs, Wi-Fi strings, plain text), PNG output considerations for print, and a testing workflow before you ship QR assets to users.
Who this course is for
- Developers generating QR codes for docs, runbooks, or internal tools
- Support and ops teams publishing Wi-Fi or onboarding codes
- Anyone who needs reliable scans without uploading content to a third-party generator
What you will learn
- What a QR code stores and how scanners interpret it
- Error correction levels L/M/Q/H and when to raise redundancy
- URL, text, and Wi-Fi payload patterns that scan reliably
- PNG size, contrast, and quiet-zone habits for print and slides
- A pre-publish scan checklist for real devices and lighting
