Walk the EdTech aisle and the pitch is always the same: to modernise a classroom, give every student a device. It’s expensive, it’s a management headache, and a growing number of educators and parents are uneasy about more screen time for children. The assumption underneath the pitch is that engagement requires a gadget per child. It doesn’t.
The hidden costs of one-device-per-child
Tablets and Chromebooks carry costs that rarely make the brochure: procurement and replacement, breakage and theft, charging and storage, distraction and content control, and the digital divide between families who can and can’t keep up. For most institutions, the device is the single biggest barrier to going “smart.”
Engagement without the gadget
The breakthrough is realising that what a smart classroom actually needs is fast, universal student response — not a screen each. With a contactless card per student and a single device in the teacher’s hand, you get:
- 100% participation in every question, instantly.
- Real-time, colour-coded understanding for the teacher.
- Attendance, quizzes and feedback — with zero devices for students.
Lower cost, wider reach
Because the model removes the per-student device, it scales to government schools and large colleges that one-device-per-child never could. The technology disappears into the lesson — which is exactly where it belongs.
AR-Tag Pulse Cards
TedQu turns any classroom into a smart classroom using AR-tag Pulse Cards — universal engagement, attendance and assessment, driven from one teacher device, with no electronic gadgets in students’ hands.
