Fintech KYC Flows: Recreating ID Verification UIs with AI-Powered Code Generation

TL;DR: Replay leverages AI to reconstruct fully functional KYC flows from video recordings, streamlining fintech development and ensuring accurate replication of user experiences.

The current crop of UI generation tools are stuck in the stone age, relying on static screenshots that miss the crucial element: user behavior. Fintech companies, in particular, face immense pressure to create seamless and secure Know Your Customer (KYC) flows. These flows are notoriously complex, requiring pixel-perfect accuracy and adherence to strict regulatory guidelines. Capturing that complexity from a mere image is a fool's errand.

The Problem: Screenshot-to-Code Falls Flat#

Building effective KYC flows is a painstaking process. Developers often spend weeks, even months, meticulously crafting each step, ensuring compliance and optimizing the user experience. Screenshot-to-code tools promise to accelerate this process, but they fundamentally misunderstand the challenge. They treat the UI as a static image, ignoring the dynamic interactions and behavioral nuances that define a successful KYC flow.

Consider a simple ID verification step. A screenshot can capture the layout of the form, but it can't capture:

• •The order in which users typically fill out the fields.
• •The error handling logic for invalid input.
• •The subtle animations and feedback mechanisms that guide the user.

These behavioral elements are critical to the overall user experience and regulatory compliance. Without them, the generated code is just a pretty picture – not a functional KYC flow.

Replay: Behavior-Driven Reconstruction#

Replay takes a radically different approach. Instead of relying on static screenshots, it analyzes video recordings of real users interacting with existing KYC flows. This allows Replay to understand not just what the UI looks like, but how users interact with it. This "behavior-driven reconstruction" is the key to generating truly functional and accurate code.

Replay's AI engine, powered by Gemini, reconstructs the UI, taking into account:

• •User actions: Clicks, taps, keystrokes, and gestures.
• •Data flow: How data is entered, validated, and transmitted.
• •State transitions: How the UI changes in response to user actions.
• •Timing and animations: The visual cues that guide the user.

This comprehensive understanding allows Replay to generate code that accurately replicates the behavior of the original KYC flow, ensuring a seamless and compliant user experience.

Replay Features in Action#

Replay isn't just a theory; it's a powerful tool with a range of features designed to streamline fintech development:

• •Multi-page generation: Reconstruct entire KYC flows, not just individual screens.
• •Supabase integration: Seamlessly connect generated code to your backend.
• •Style injection: Customize the look and feel of the UI with your own CSS.
• •Product Flow maps: Visualize the entire KYC process, identifying potential bottlenecks and areas for improvement.

Replay vs. The Competition: A Head-to-Head Comparison#

The difference between Replay and traditional screenshot-to-code tools is stark. Here's a breakdown of how Replay stacks up:

💡 Pro Tip: Don't waste time debugging non-functional code. Replay delivers working UI from the start.

Building a KYC Flow with Replay: A Step-by-Step Guide#

Here's how you can use Replay to recreate an ID verification UI:

Step 1: Record the User Flow#

Record a video of a user completing the ID verification process. This could be a screen recording of an existing app or a prototype. The clearer the recording, the better the results.

📝 Note: Ensure the video captures all user interactions, including form submissions, error handling, and loading states.

Step 2: Upload to Replay#

Upload the video to the Replay platform. Replay's AI engine will automatically analyze the video and reconstruct the UI.

Step 3: Review and Customize#

Review the generated code and make any necessary adjustments. You can use Replay's style injection feature to customize the look and feel of the UI.

Step 4: Integrate with Your Backend#

Integrate the generated code with your backend using Replay's Supabase integration. This will allow you to connect the UI to your existing data models and business logic.

Example: Reconstructing a Form Field with Error Handling#

Here's an example of the code Replay can generate for a form field with error handling:

typescript
// TypeScript example
import React, { useState } from 'react';

const NameInput = () => {
  const [name, setName] = useState('');
  const [error, setError] = useState('');

  const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const value = e.target.value;
    setName(value);

    if (value.length < 3) {
      setError('Name must be at least 3 characters long.');
    } else {
      setError('');
    }
  };

  return (
    <div>
      <label htmlFor="name">Name:</label>
      <input
        type="text"
        id="name"
        value={name}
        onChange={handleChange}
      />
      {error && <p className="error">{error}</p>}
    </div>
  );
};

export default NameInput;

This code snippet demonstrates how Replay captures not just the input field itself, but also the error handling logic that is crucial for a functional KYC flow.

Scaling KYC Development with Replay#

Replay empowers fintech companies to:

• •Accelerate development cycles: Reduce the time it takes to build KYC flows by up to 80%.
• •Improve accuracy and compliance: Ensure that the generated code accurately reflects the behavior of the original UI, minimizing the risk of errors and compliance violations.
• •Enhance user experience: Create seamless and intuitive KYC flows that improve user satisfaction and reduce drop-off rates.
• •Reduce development costs: Lower the cost of building and maintaining KYC flows.

⚠️ Warning: Failing to accurately replicate user behavior in KYC flows can lead to compliance issues and financial penalties.

The Future of UI Development is Behavior-Driven#

The shift from screenshot-to-code to behavior-driven reconstruction is a paradigm shift in UI development. Replay is at the forefront of this revolution, empowering developers to build more accurate, functional, and user-friendly applications. By understanding how users interact with UIs, Replay unlocks a new level of efficiency and accuracy in the development process.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for more advanced features and higher usage limits.

How is Replay different from v0.dev?#

V0.dev generates UI components based on text prompts. Replay, on the other hand, analyzes video recordings to reconstruct entire UI flows, capturing user behavior and ensuring functional accuracy. V0.dev is great for quick prototyping; Replay is ideal for replicating complex, real-world UIs.

Can Replay handle complex animations and transitions?#

Yes, Replay's AI engine is capable of analyzing and reconstructing complex animations and transitions.

What types of videos can Replay analyze?#

Replay can analyze screen recordings, mobile recordings, and even videos of users interacting with physical devices.

How secure is Replay?#

Replay uses industry-standard security measures to protect your data. All videos are encrypted and stored securely.
