Requirements Clarification & Assessment

1. Precision Level

   • Determine the level of precision required for the residence location: city, neighborhood, postal code, or specific address.
   • Understand the privacy constraints and legal boundaries surrounding the use of credit card data.

2. Data Accessibility

   • Identify the available data fields, such as transaction location, time, merchant category, and billing address.
   • Confirm if the data is anonymized and if there are any restrictions on accessing specific data points.

3. User Behavior Understanding

   • Assess user behavior patterns, such as frequent purchases, recurring transactions, and time of transactions.
   • Determine if the data includes only credit card transactions or if it is supplemented with other payment methods.

4. Objective

   • Clarify the context in which the residence determination is needed, such as for marketing, fraud detection, or service personalization.

5. Ethical and Legal Considerations

   • Ensure compliance with data protection laws and ethical guidelines in handling and analyzing credit card data.
   • Consider user consent and the implications of using personal data for residence determination.
