What is a QR code?
A QR code is a two-dimensional scannable code that can store information such as a website URL, text, contact details, WiFi network details, event information, or a feedback link.

What is a barcode?
A traditional barcode is often a one-dimensional pattern of lines used for product identification, inventory, retail checkout, and tracking workflows.
Main differences
QR codes are two-dimensional and can store more varied content for everyday digital workflows. Traditional barcodes are commonly used for product and inventory identifiers.
- QR codes use square modules
- Many barcodes use vertical line patterns
- QR codes commonly open links or store structured details
- Barcodes are common in retail and logistics
Why QR codes are useful
QR codes are useful because they can bridge printed or on-screen content with Android actions such as opening a link, saving a contact, sharing WiFi details, or checking in at an event.
