The Power of QR Codes
Quick Response (QR) codes are two-dimensional barcodes that can be scanned using a smartphone camera. Originally invented in 1994 by Denso Wave for tracking automotive parts, they are now ubiquitous in marketing.
This tool generates Static QR Codes. The data you enter is directly encoded into the pattern of black and white squares. This means the code will work forever and requires no internet connection to function (unless it's a URL).
Best Practices
- Contrast is Key: Scanners look for contrast. Dark on Light is standard. Light on Dark often fails.
- Size Matters: Ensure the QR code is at least 2cm x 2cm (0.8in) when printed.
- Error Correction: QR codes have built-in redundancy. Even if up to 30% of the code is damaged (or covered by a logo), it can still be scanned.
