Education Technology

Seamless Proximity & Engagement Tools for the Modern EdTech Stack

Empower your platform with hardware-agnostic connectivity and gamification features that turn any student device into a high-value touchpoint. 

LISNR’s ultrasonic technology, Radius, is transforming how ed tech softwares engage and reach students before, during, and after classes. When combined with LISNR’s Quest loyalty platform, Ed tech softwares can offer schools gamified and personalized learning experiences that increase attention and long-term retention of educational materials.

Your Software’s Next High Value Differentiation

LISNR’s Radius product establishes a direct communication channel between the teacher and their students using their existing devices, no specialized hardware or complex pairing required. By detecting proximity to students’ devices, ed tech software can enable frictionless attendance verification, personalized learning experiences, and gamified curriculum.

LISNR expands the experience for students with a loyalty management portal, Quest. By adding a loyalty component, schools can gamify learning experiences, increase compliance, and improve long-term retention of educational material.

Verification Method

How are students interacting with the attendance verification?

★ ★ ★ ★ ★

High-frequency, inaudible sound waves. Data-Over-Sound 

★ ★ ★ ★ ★

Visual scanning of a 2D code. Students check-in at the start of class.

★ ★ ★

Students mark themselves as present via BLE connection

User Friction

How long does it take to mark all students as present for class?

★ ★ ★ ★

Zero-to-Low. Phone "hears" the room and checks in automatically.

★ ★

Medium. Students pull out phone, open app/camera, and align with code.

★ ★ ★

Medium-to-High. Students need to check-in to class themselves

Hardware Needed

What uplift is required for virtual attendance tracking

★ ★ ★ ★

Existing. Speakers and microphones are present in standard devices.

★ ★ ★

Screen + Camera. Users pull out devices and scan the code on screen.

★ ★

Beacons + Devices. Students need devices with BLE Beacons.

Security

How secure and accurate is the attendance verification protocol?

★ ★ ★ ★ ★

High. ToneLock & Encryption protect against fraud and spoofing.

★

Low. Students need mobile devices and can share the QR outside of class.

★ ★

Low-to-Medium. Students nearby to the classroom can be marked present.

Connectivity

How does the solution work for all environemnts (Hybrid/Remote)?

★ ★ ★ ★ ★

High. Works without data connectivity during the actual data-exchange.

★ ★ ★

Required. Dynamic QR Codes require data connection.

★ ★

Required. Connectivity required for BLE attendance verification.

Attendance Verification

Complete attendance in the first 10 seconds of class.

  • Increase reliability in students’ attendance
  • Reduce time spent on attendance tracking
  • Streamline attendance solutions

With Radius, students can check in at their desk in the first 10 seconds of class. Radius’ built in security features reduce fraud and prevent replay attacks (students trying to record the attendance tone). With reduced time spent on attendance, teachers can focus on what matters.

Access Control

Radius also serves as an access-control modality, limiting entry to private areas without needing physical locks and keys. Restricted areas for teachers, dorm rooms, cafeteria credentials, and even university dollars spent on vending machines can all be sent through Radius securely.

  • Streamline credential passing
  • Enable teacher-only access areas
  • Verify device presence without a network

With ultrasonic access control, schools can protect high-value credentials and enable staff-only workflows without relying on barcodes, QR codes, or connectivity.

Shared Screens

Logging into a shared screen can be made easier and more secure with Radius. Instructors can login to a shared device by sending passwords securely over sound rather than typing them publicly and risking exposure.

  • Reduce sharing of access codes
  • Provide consistent experiences across screens
  • Eliminate presentation delays

Ensure secure, real-time device pairing or login via short-range credential passing. Students can also be authenticated and allowed to share to screens when prompted.

Wayfinding

Integrate a sound-based wayfinding solution into your student app using Radius. Ensure students are in the correct classroom and on time by providing real-time directions or enable self-guided campus tours. 

  • Provide wayfinding solutions 
  • Personalize in-campus experiences
  • Create scavenger hunts on campus

Ultrasound makes it possible to run interactive engagements with students on-campus without beacons, NFC, or specialized hardware, just standard speakers and mics.

Gamification

The Quest platform allows Ed Tech companies to easily incorporate gamification elements via a simple API and management portal.

  • Incentivize the most impactful student actions
  • Gamify the in-school learning experience with proximity identification

 

LISNR reimagines how and where schools’ learning programs interact with students across their education journey. By gamifying the educational experience, students can earn points at any digital touchpoint. By creating an engaging learning experience for young students, schools can see an increase in students’ connectivity with their education material
