Role: Lead Technical Product Manager, In-Store Digital Experience

Context

• Store environment: {{store_format_type}}
• Membership structure: {{loyalty_tier_model}}
• Customer receipt channels: {{receipt_delivery_channels}}
• Checkout speed threshold: {{cashier_interaction_budget}}
• Regulatory and data requirements: {{compliance_jurisdiction}}
• Network resilience parameter: {{offline_handling_rule}}

Task

Generate a functional requirements specification for the in-store point-of-sale software to enable instant digital receipt generation, phone or NFC customer identification, and loyalty reward crediting within {{store_format_type}} locations.

Method

1. Define customer identification pathways at terminal (NFC tap, QR scan, phone lookup) tailored to {{store_format_type}}.
2. Establish the profile matching logic against {{loyalty_tier_model}} to calculate earn rates instantly.
3. Specify the receipt payload structure and dynamic formatting for {{receipt_delivery_channels}}.
4. Map the UI prompts for the customer-facing display to maintain the {{cashier_interaction_budget}} limit.
5. Formulate tax, legal disclaimer, and itemized data requirements mandated by {{compliance_jurisdiction}}.
6. Architect local transaction queueing and sync recovery following {{offline_handling_rule}}.
7. Detail cashier override workflows for incorrect phone numbers or customer opt-out requests.

Constraints

• Checkout interaction steps MUST stay strictly within {{cashier_interaction_budget}}.
• Digital receipts MUST NOT omit mandatory legal fields specified by {{compliance_jurisdiction}}.
• Customer personally identifiable information (PII) MUST NOT be stored in cleartext on the local POS cache.
• Terminal offline recovery MUST execute automatically when network connectivity is restored per {{offline_handling_rule}}.
• Keep the total specification length under 700 words.

Output format

1. Workflow & Sequence Overview
2. POS Terminal User Interface Requirements
3. Data Payload & Dispatch Specification
4. Offline Mode & Fault Tolerance
5. Compliance & Security Controls

Self-review

• Verify that step durations do not exceed the {{cashier_interaction_budget}}.
• Ensure dispatch payload supports all options in {{receipt_delivery_channels}}.
• Check that compliance requirements reflect {{compliance_jurisdiction}} tax and privacy standards.
