Best Practices

1. Use Specific Fields: Access only the fields you need (e.g., finance.iban)
2. Combine with Choice: Use choice generator for payment types, currencies, statuses
3. Add Validation Fields: Combine with string generator for CVV, expiry dates
4. Create Relationships: Link accounts to users, transactions to accounts
5. Realistic Amounts: Use float generator with appropriate min/max for balances and amounts

Security Note

Important: The generated financial data is for testing purposes only. These are randomly generated numbers that may not pass real validation algorithms. Do not use this data for:

• Production systems
• Real financial transactions
• Fraud testing without proper authorization
• Any system that processes real money

Use Cases

• Banking Applications: Generate test accounts and transactions
• Payment Systems: Create payment method test data
• E-commerce: Generate order and payment data
• Financial Reporting: Create test data for reports and analytics
• Testing: Populate test databases with realistic financial data

Comparison with Other Generators

Generator	Use Case
Finance	Banking and payment data
Number	Generic numeric values
Float	Decimal amounts (prices, balances)
String	Custom formatted strings
UUID	Unique identifiers

Next Steps

• Float Generator - For monetary amounts
• String Generator - For custom financial codes
• References - Link accounts to users
