In the current digital landscape, age verification and user authentication are crucial for e-commerce, online games, financial services and content platforms. Traditional methods such as passwords and OTP codes often introduce inefficiencies and security issues, impacting the user experience. FACEIO, a robust facial recognition solution, offers an efficient and secure alternative, allowing the direct integration of authentication and age verification into applications.

This guide demonstrates implementing FACEIO in a React app for facial authentication and age verification. In the end, you will have a functional application that uses this technology to authenticate users in a secure and simplified way.

Benefits of FACEIO in Age Verification:

FACEIO optimizes the complex task of authentication and age verification with:

• Simple Integration: Uses a simple JavaScript script or NPM package for easy implementation.
• Enhanced Security: Eliminates vulnerabilities associated with passwords and credentials.
• Fluid Experience: No need for passwords or PINs, improving usability.
• Accurate Age Detection: Verifies user age with high accuracy during authentication.

Step 1: Configuring your React Application

Create a React application and install the FACEIO NPM package:

npx create-react-app faceio-age-verification
cd faceio-age-verification
npm install @faceio/fiojs

More information about the NPM package is available on the FACEIO page on NPM.

Step 2: Integration of FACEIO into React

Follow the code to integrate FACEIO with your React application:

import React, { useState } from "react";
import FACEIO from "@faceio/fiojs";

const FaceAuth = () => {
  const [age, setAge] = useState(null);
  const [status, setStatus] = useState("");

  const handleFaceAuth = async () => {
    const fio = new FACEIO("SUA_FACEIO_APP_ID_PUBLICA"); // Substitua pelo seu ID Público do FACEIO

    try {
      const response = await fio.authenticate({
        locale: "auto",
      });

      console.log("Autentica??o bem-sucedida:", response);
      setAge(response.age);
      setStatus(`Autentica??o Bem-sucedida. Idade: ${response.age}`);
    } catch (error) {
      console.error("Falha na autentica??o:", error);
      setStatus("Falha na autentica??o. Por favor, tente novamente.");
    }
  };

  return (
    <div>
      {/* ... restante do código ... */}
    </div>
  );
};

Step 3: API Response and Age Verification

The FACEIO API returns user data, including age. Example answer:

{
  "status": 200,
  "age": 25,
  "timestamp": "2025-01-25T10:00:00Z",
  "auth_token": "abcdef1234567890",
  "face_image_url": "https://cdn.faceio.net/faces/123456.jpg"
}

The "age" field is used to verify the user's age.

Step 4: Running the Application

Run the application with:

npm start

Go to http://localhost:3000 and click "Authenticate" to test facial recognition.

Use Cases:

FACEIO is applicable in several areas:

• E-commerce: Age verification for restricted products.
• Online Games: Age restrictions apply.
• Streaming: Controlling access to age-restricted content.
• Financial Services: Biometric security for login.

Error Handling and Good Practices:

• Error Handling: Implement proper error handling such as checking for invalid API keys.
• API Key Security: Store your API keys securely using environment variables.
• Testing: Run comprehensive tests in different environments.
