Frequently Asked Questions

Do QR codes generated by ASToolHub ever expire?

Never. ASToolHub creates permanent static QR codes where your data is encoded directly into the pixel pattern. There are no redirect servers, no expiration dates, and no monthly fees.

How does the Wi-Fi QR code work?

When scanned by iOS or Android cameras, the encoded Wi-Fi string prompts the user to join the network automatically without manually typing the password.

Which error correction level should I choose for printing?

Choose Level Q (25%) or Level H (30%) if you plan to print your QR code on physical menus, business cards, or outdoor signs to ensure scanability despite smudges or scratches.
