VisionPay: AI-Powered Payments
VisionPay is a concept project that merges AI, blockchain, and computer vision into a secure and intelligent payment platform. It leverages the Raspberry Pi 5, a Hailo AI acceleration module, and a camera module to process transactions in real-time while recording them on a blockchain.
🛠 Hardware Setup
- Raspberry Pi 5 (8GB recommended)
- Hailo AI Acceleration Module (Hailo-8 or Hailo-8L)
- Raspberry Pi Camera Module (Camera Module 3 or High-Quality Camera)
- Optional: Additional hardware for blockchain node hosting
⚙️ Software Setup
- Raspberry Pi OS (64-bit) — Install via Raspberry Pi Imager.
- Update System
sudo apt update
sudo apt full-upgrade
- Set PCIe to Gen3 for optimal AI performance.
- Hailo SDK — Install from the Hailo GitHub repository.
- Python API — Use the Hailo Python API for AI inference.
📷 Camera Configuration
Follow the Raspberry Pi Camera Guide to connect and enable the camera module.
🤖 AI + Blockchain Workflow
- Capture Data — Camera captures images of transactions or QR codes.
- AI Processing — Hailo module processes object detection, QR scanning, or identity verification.
- Blockchain Recording — Transactions are recorded immutably using a blockchain ledger.
Example Python snippet for detection + blockchain logging:
import cv2
import hailo_sdk
from flask import Flask, jsonify
hailo = hailo_sdk.Hailo()
app = Flask(__name__)
blockchain = []
@app.route('/detect', methods=['POST'])
def detect():
cap = cv2.VideoCapture(0)
ret, frame = cap.read()
cap.release()
detections = hailo.detect(frame)
block = {'index': len(blockchain)+1, 'detections': detections}
blockchain.append(block)
return jsonify(block)
app.run(host='0.0.0.0', port=5000)
💳 Payment Integration
- QR Code Capture — Using OpenCV + Pyzbar to read QR payment codes.
- Blockchain Ledger — Store transactions for transparency and immutability.
- Smart Contracts — Automate transaction validation and payment release.
🌍 Blockchain Options
- XRP (Ripple) — Fast cross-border transactions with low fees.
- XLM (Stellar) — Low-cost payments and asset tokenization support.
- Ethereum / Polygon — Smart contract flexibility.
📈 Potential Use Cases
- Retail & Point-of-Sale payments
- Peer-to-peer microtransactions
- Cross-border remittances
- Automated contract-based billing
📝 Executive Summary
VisionPay is positioned to become a next-gen payment platform by:
- Leveraging AI for real-time verification.
- Using blockchain for transparency and security.
- Supporting fast, low-cost payments via XRP, XLM, or other networks.
This concept represents a future-ready fintech solution where AI meets secure, decentralized payments.
