QR (Quick Response) codes are two-dimensional barcodes. They are an easy way of giving information just by having someone hold up a smartphone: you can take someone to a web site, give them contact information, or just show some text.
If you’ve never used QR codes, it’s easy to get started:
- Put a QR code reader on your smartphone. (See list below.)
- Run the app and use your phone’s camera to scan the code.
- See where the QR code takes you!
