Sure. As I mentioned, there are more than a hundred mask map visualizations. And so it's not a single platform. It is rather a protocol, a way for platforms to talk to each other, the way for pharmacies to report their real-time stock inventory of masks available. Another protocol for venues to post out random numbers and a QR code that if you scan, it sends that 15-digit random number to 1922, to your local telecom. But then the venue just sees that you have scanned the code and sent the SMS. It doesn't learn anything about you. It doesn't even learn about your phone number. Your telecom operator knows nothing about the venue because it's a random number, and the state learns nothing. But then it is still able, then through the cooperation of all these telecoms in Taiwan, do exposure notification that has served us very well to Omicron. So it is not a single platform that people have to be on. It is a protocol for a platform to talk among themselves.
