Can QR codes work without internet access?

QR codes themselves require an internet connection to reach the linked content. However, the QR code itself is just a link — if students are on a local school Wi-Fi network, the content only needs to be accessible on that network.

How do I create QR codes for a whole class set of assignments?

Use the Online-QR API programmatically. For example, if each assignment has a unique ID in your LMS, generate a QR for each one by calling the API with `data=https://lms.yourschool.edu/assignments/{id}`. This can be automated in a script or spreadsheet formula.

Are QR codes safe for students to use?

QR codes generated by educators pointing to school-managed domains are safe. Instruct students to only scan QR codes provided by teachers and to verify the URL shown after scanning before proceeding, as a general digital literacy practice.

How Online-QR Helps Education Businesses

Generate, track, and manage QR codes for your entire operation with a single API endpoint.

Enrich Printed Materials Digitally

Textbooks and worksheets have a fixed amount of space. A QR code extends that resource digitally — linking to videos, simulations, and interactive content that print cannot deliver.

Reduce Administrative Overhead

QR codes on assignment sheets, registration forms, and campus notices reduce the need for manual distribution and repeated verbal instruction.

Accessible on Any Device

Students with smartphones, tablets, or laptops can all access QR-linked content without logging into a specific platform. The camera app does all the work.

Update Content Without Updating Print

Dynamic QR codes allow teachers to update linked resources each academic year without reprinting workbooks. A single code can serve fresh content term after term.
