Real Time Vision Payment Assistant using A2A, AP2 mandates, Hedera Agent Kit and PYUSD

VisionPay AI-Powered Autonomous Payment Assistant Like Ray-Ban Meta glasses meets Apple Pay - AI watches your world and handles payments intelligently.
VisionPay Blockchain Protocol
🎯 The Vision Imagine wearing smart glasses that let you pay for things just by looking at them. Point your camera at a coffee shop logo, and your AI assistant handles the payment automatically based on rules you set. No phone, no wallet, no buttons.
VisionPay brings this future to today.
✨ How It Works
Set Payment Rules "Auto-pay coffee shops under $10" "Auto-pay transit fares under $5" "Always ask for restaurants over $20"
Point Your Camera The AI continuously watches through your camera (or wearable device), detecting vendor logos and signs in real-time.
Agent Decides When a vendor is detected, the autonomous agent checks your payment rules:
Match found? → Pays automatically with HBAR or PYUSD No match? → Asks for your approval No button clicks needed. Just point and go.
