In this short demonstration, Speaker A explains and showcases a novel biometric security feature for authorizing payments. The system requires the user to form a specific fist and align a knuckle at a precise distance, creating a unique hand geometry that the device can detect. The speaker emphasizes that the feature will not activate if the hand is positioned incorrectly or if the device is moved, preventing accidental or spoofed transactions. After the user forms the correct fist, they press a "collect" button, receive an on‑screen prompt, and maintain the hand position briefly; the system then confirms the payment instantly. The demo contrasts this method with conventional swipe‑based payments, highlighting its intentionality and resistance to unintended activation.

We have a security feature. If you keep it like this, or if let's say I'm unaware, I'm talking to somebody, somebody brings my machine like this, it will not transmit. So you have to create a fist and then align my knuckle on top of it so that it comes in that specific distance away. Exactly. The whole circle. Exactly. It cannot work here. It cannot work here, here, here. It will not work like you swipe. So you want to give it a shot? Yeah, I'd love to. I hope it fits you. I mean, I'll try it on a finger that probably— No, I think the smaller one. Go for this one. This finger there. How about that? When I Press collect. Collect. Okay, you, you have a prompt on the screen. Just keep your hand that way for— that's it, done. And your payment is done.
