Get Started FreeQR codes (Quick Response codes) are two-dimensional barcodes that store information in a matrix of black and white squares. Originally invented in 1994 by Denso Wave for tracking automotive parts, QR codes have since become a universal tool for connecting the physical and digital worlds. Unlike traditional one-dimensional barcodes that store data in a single row of lines, QR codes encode data both horizontally and vertically, allowing them to hold significantly more information -- up to 7,089 numeric characters or 4,296 alphanumeric characters. They can be scanned instantly by any smartphone camera, making them an ideal bridge between print materials, signage, packaging, and digital content like websites, menus, and contact cards.
One of the most important features of QR codes is Reed-Solomon error correction, which allows them to be read even when partially damaged, dirty, or obscured. There are four error correction levels: L (7%), M (15%), Q (25%), and H (30%). The percentage represents how much of the code can be lost while still remaining scannable. Level M is the most commonly used, providing a good balance between data density and recoverability. Level H is often used when a logo or graphic is placed over part of the QR code, since up to 30% of the modules can be covered without breaking the code. Higher correction levels make the code more reliable but also increase its physical size, as more redundant data modules are added.
For local businesses, QR codes are a powerful marketing tool. They can be printed on business cards, flyers, menus, receipts, storefronts, and vehicle wraps to instantly direct customers to your Google Business Profile, review page, website, or special offer landing page. When combined with UTM parameters, QR code URLs allow you to track exactly how many scans come from each physical location or marketing material. Best practices include making QR codes at least 2cm x 2cm for reliable scanning, ensuring high contrast between foreground and background colors, and always testing the code with multiple scanner apps before printing. Adding a short call-to-action near the code (like "Scan for menu" or "Leave us a review") significantly increases scan rates.
