Yes. You can enter multiple lines of text, with each line corresponding to one QR code or barcode, and the system will generate all results at once. After generation, you can download them individually or as a batch package, making it ideal for scenarios requiring large-scale production.
QR codes are ideal for storing larger amounts of information, such as website links, digital business cards, WiFi passwords, social media profiles, product details, event check-ins, and mobile payments. Barcodes are better suited for retail products, inventory management, logistics tracking, library systems, pharmaceutical management, and ticket validation where fast scanning is essential.
QR codes are two-dimensional, storing data both horizontally and vertically, which gives them high capacity for letters, numbers, and even Chinese characters. They also have high error correction, meaning they can still be scanned even if partially damaged. Barcodes are one-dimensional, storing data only horizontally with limited capacity (mostly numbers), and typically require dedicated scanners or specific apps to read.
