What information is required to generate Bank QR codes for payments?

To create Bank QR codes for payment processing, you need to provide essential banking information: bank name, account number, and account holder name. For international transfers, you can optionally include SWIFT/BIC codes. Our system validates all required fields to ensure the payment information is correctly formatted and compliant with banking standards. This creates secure, scannable payment QR codes for businesses and individuals.

How secure are WiFi QR codes? Is it safe to share network credentials?

WiFi QR codes are secure when shared responsibly. The QR codes contain your network credentials (SSID and password), so only share them with trusted individuals like guests, employees, or family members. Our QR generator processes all information locally in your browser - no data is stored on our servers, ensuring your WiFi credentials remain private. The generated QR codes use standard WiFi QR format compatible with all devices.

Can I download high-quality QR codes for printing and professional use?

Absolutely! Once you generate any QR code, you can instantly download it as a high-resolution PNG image file by clicking the 'Download QR Code' button. Our QR codes are optimized for both digital use and professional printing, ensuring crisp, clear images suitable for business cards, posters, marketing materials, and large-format printing. The downloaded images maintain excellent quality at any size.

Do QR codes expire? How long do generated QR codes remain functional?

QR codes generated by our platform never expire and will work indefinitely. Once created, they remain functional permanently as long as the encoded information stays valid. For example, URL QR codes work as long as the website remains active, and WiFi QR codes work as long as the network credentials are unchanged. Static QR codes (text, contact info) work forever without any dependencies.

What's the optimal size for QR codes? How do I ensure best scanning performance?

For optimal scanning performance, QR codes should be at least 2x2 cm (0.8x0.8 inches) when printed. Our generator creates QR codes that scale perfectly - larger sizes improve scanning reliability, especially from distance. Ensure high contrast between the QR code and background, maintain adequate white space around the code, and test scanning from various devices before final use. Our high-resolution downloads ensure crisp printing at any size.

Can I generate multiple QR codes at once for batch processing?

While our current interface focuses on individual QR code creation for optimal customization, you can quickly generate multiple QR codes by using different tabs for various types (Text, URL, WiFi, Bank, vCard). Each QR code can be customized independently and downloaded separately. For businesses needing bulk QR generation, our streamlined interface allows rapid creation of multiple codes with consistent branding and design.
