EchoTransact Voice Commerce Payment Flow

Introduction

This UX Flow Diagram document outlines the user experience for EchoTransact's voice-initiated payment solution. EchoTransact bridges the critical gap between conversational commerce and secure transaction processing, allowing businesses to fully monetize their voice channels without compromising security or user experience.

The flow diagrams presented here illustrate how users move from initial voice interactions through to completed payments, the various states they encounter, and how the system responds to different scenarios. This document serves as a blueprint for implementation, highlighting key interaction points, decision branches, and feedback mechanisms that will define the EchoTransact experience.

1. System Architecture Overview

EchoTransact's voice commerce payment infrastructure consists of several interconnected components that work together to create a seamless experience across voice and mobile channels. The following diagram illustrates the high-level system architecture and key user flows:

6. Success Confirmation - Customer receives confirmation of successful payment
7. Conversation Continuation - Voice interaction acknowledges payment and continues

Decision Points

1. Purchase Intent - Does the customer want to make a purchase?
2. Payment Acceptance - Does the customer want to pay through the voice channel?
3. Number Validation - Is the provided mobile number valid?
4. Link Opening - Does the customer open the payment link?
5. Payment Validation - Is the payment information valid?
6. Authentication Preference - Which authentication method does the customer prefer?

Error States

1. Invalid Mobile Number - Number format is incorrect or unrecognized
2. Link Timeout - Customer doesn't open the payment link within the session window
3. Payment Validation Errors - Issues with payment information format or content
4. Payment Processing Errors - Issues with the payment processor or declined payment
5. SMS Delivery Failure - Unable to deliver SMS with payment link

    class C,H,K,M,O,Q,R,AC future
    
    classDef error fill:#ffcccc,stroke:#333,stroke-width:1px
    class K,R error

Key Differences from First-Time Flow

1. Customer Recognition - System attempts to recognize returning customers
2. Streamlined Authentication - Uses previously established authentication preferences
3. Saved Payment Methods - Offers to use previously saved payment information
4. Reduced Steps - Fewer steps required to complete the transaction
5. Personalized Experience - Tailored to customer's known preferences

Authentication Methods

1. SMS Verification - One-time code sent to the customer's mobile device
2. Biometric Authentication - Using device biometrics (TouchID, FaceID) for verification
3. Fallback Authentication - Alternative methods if primary method fails

4. High-Value Transaction Flow

For transactions exceeding the standard verification threshold ($100), additional security measures are implemented:

graph TD
    subgraph "Standard Flow"
        A[Payment Initiation] --> B[Standard Authentication]
        B --> C{Transaction Value Check}
    end
    
    subgraph "Enhanced Verification"

        M --> D
    end
    
    subgraph "Completion"
        D --> N[Complete Transaction]
        N --> O[Send Enhanced Receipt]
    end
    
    classDef mvp fill:#d4f1f9,stroke:#333,stroke-width:1px

    class E,G,H,I,J,K,M security
    
    classDef error fill:#ffcccc,stroke:#333,stroke-width:1px
    class L error

Enhanced Security Measures

1. Transaction Value Threshold - Automatically triggers enhanced verification for transactions over $100
2. ID Document Verification - Requests and verifies government-issued ID
3. Knowledge-Based Authentication - Additional security questions based on customer information
4. Multi-Factor Authentication - Combines multiple verification methods
5. Enhanced Fraud Monitoring - Additional checks for suspicious patterns

User Experience Considerations

1. Clear Explanation - Customers receive clear explanation of why enhanced verification is required
2. Streamlined Process - Verification designed to be as frictionless as possible while maintaining security
3. Progress Indication - Clear indication of verification progress and remaining steps
4. Alternative Options - Multiple verification paths to accommodate different situations
5. Timeout Management - Appropriate handling of verification session timeouts

5. Error Recovery Flows
