Let’s break it down

Now more than ever customers want to feel safe in a COVID-19 world. With the Broadcast SDK create frictionless check-in and locationing experiences to maximise social distancing and drive efficiency.

Step 1
Link a location with an audio-code

The smart-device emits an ultrasonic audio-code, creating a sonic-sphere unique to that location. You can fill an entire room by playing the code out of a speaker.

Step 2
User arrives at the location and detects the audio-code

The user is at the right location and needs to verify their presence. They can do this by opening an app or clicking a URL link sent through SMS or email. Now their phone detects the audiocode.

Step 3
Our server verifies the user’s presence

Our server analyses the audio-code, matches it to the site and returns a token. You now know your customer is where they’re supposed to be, and they’ve verified their presence seamlessly.

Optimise social distancing

Allow users to verify anywhere and avoid common points of contact (like touch pads and screens).

Unlimited customer verification

There’s no limit to the number of customers you can verify in the sonic-sphere.

VIEW DOCUMENTATION
A little goes a long way

We’ve made the Broadcast SDK as simple to integrate as possible, with step by step documentation to get you where you need to be.

To maximise the Broadcast potential we’ve also made it easy to use existing infrastructure, like on-site speakers or smart-terminals. As long as the device can emit and receive sound you’re good to go. You can customise the range of your sonic-sphere so that verification can happen within centimetres or metres.

So who said innovation needs to cost the earth?
