QR Code vs Barcode: Differences and Use Cases

Basic differences

Barcode (1D): Carries information in one dimension. Stores 20-25 characters. Made of lines and spaces. Read with a scanner.

QR code (2D): Carries information in two dimensions. Stores 4000+ alphanumeric characters. Made of square modules. Read with a camera.

Data capacity: QR code can store 100 times more data than a barcode. Can store complex data like URL, text, Wi-Fi, vCard.

Error correction: Barcodes cannot correct errors (damaged barcode cannot be read). QR codes have 7-30% error correction capacity.
