# Comprehensive Product Requirements: Fan Passport — The World Cup Journey

## 1. Product Summary

**Fan Passport** is a digital football passport for FIFA World Cup 2026 that turns the tournament into a daily journey. Fans collect teams, matches, stadiums, predictions, achievements, trivia answers, and memories while competing on leaderboards and unlocking badges.

The product is designed to evolve after the tournament into a broader football fan rewards ecosystem, starting with Premier League Passport and Champions League Passport.

## 2. Product Vision

Fan Passport should become the daily habit layer around major football competitions.

It should answer three user questions every day:

1. **What should I do today?**  
   Check in, make predictions, answer trivia, collect items, follow fixtures.

2. **How is my journey growing?**  
   Passport stamps, badges, levels, collections, completed groups, stadiums, match memories.

3. **How do I compare and share?**  
   Leaderboards, friend comparisons, share cards, prediction accuracy, collection progress.

## 3. Product Goals

## 14. Key Product Rules

### 14.1 Time Rules

- If kickoff changes before lock, prediction lock moves with the new kickoff time.
- If kickoff changes after lock, predictions remain locked unless admin explicitly reopens them due to major postponement.

### 14.2 Scoring Rules

- Passport Points measure competitive tournament performance.
- XP measures personal participation and level progression.
- Badges can award both XP and Passport Points, but high-value points should be attached to skill or completion rather than passive login volume.

### 14.3 Completion Rules

- A user completes a group if they collect all teams in that group and stamp or predict a defined number of group matches.
- A user completes a stadium if they collect its stadium item and stamp at least one match hosted there.
- Tournament completion is intentionally aspirational and should be possible without attending matches physically.

### 14.4 Rights and Licensing Rules

- If official FIFA marks, tournament logos, team crests, kits, player likenesses, or broadcast imagery are used, the operator must have the appropriate rights.

| Rights restrictions limit visuals | Product feels less official | Original art direction, neutral passport metaphor, licensed data/content |

## 18. Product Principles for Future Teams

1. **Every action should stamp the journey.**  
   Avoid generic tasks that do not feel connected to football or the tournament.

2. **Completion should be ambitious but humane.**  
   Users should feel challenged, not punished for having real lives.

3. **Competition must be explainable.**  
   Any leaderboard score should be understandable from a user’s history.

4. **Collections should reduce frustration over time.**  
   Duplicates and rarity create excitement only when users can still progress.

5. **The product should survive team elimination.**  
   National identity is a starting point, not the only reason to return.

6. **The World Cup passport becomes a memory artifact.**  
   Do not erase the journey when the tournament ends.

7. **Future passports share identity but respect competition differences.**  
   Premier League and Champions League should reuse systems while adapting to their calendars and fan behaviors.
