Barcode vs QR Code — What's the Difference?
Traditional barcodes (1D) store data as a series of vertical lines of varying widths and are read by laser scanners. They can only encode a small amount of numeric or alphanumeric data. QR codes (2D) store data in a grid pattern and can encode URLs, text, contact cards, and much more — they are read by smartphone cameras. Use 1D barcodes for retail/logistics scanning, and QR codes when you need to encode URLs or more complex data for consumer scanning.
