AppVisitanos - Smart City Tourist Application Development

AppVisitanos – Technical Specification
1. Executive Summary

AppVisitanos is a cloud-native digital ecosystem (PWA) that turns the City into a Smart Tourism Destination.
Through an official city QR Code, visitors access:

Tourist safety tools (SOS button with geolocation + silent protocol).

Smart local economic activation (geo directory, coupons, digital passport, gamification).

Real-time tourism intelligence for government (heatmaps, visitor flow, campaign impact).

Built with a PWA front-end, serverless architecture, API-First design, and government-grade cybersecurity. AI is used for semantic search, analytics, and predictive geolocation.

2. Vision & Scope

AppVisitanos becomes the city’s official digital layer.
Key goals:

Frictionless adoption (no app store; instant access via QR).

Scalability for peak seasons.

Foundation for Smart City evolution.

3. System Architecture

Third parties: Google/Apple Maps, Tripadvisor/Booking, WhatsApp Business API, SMS providers, ticketing systems.

3.5 Cloud Infrastructure (AWS/Azure/GCP)

Serverless (Lambdas/Cloud Functions) and/or containerized (Docker/Kubernetes).

CDN + load balancers; centralized monitoring (APM/logs).

Multi-zone replication, failover, auto-scaling.

4. Key Modules

Rewards engine (unique dynamic QR coupons).

Progress bars for routes.

Social-sharing tools.

Municipal control panel for campaigns and route analytics.

4.4 Safety Module: Tourist SOS

Always-visible SOS button (911, tourist police, Red Cross, consulates).

Geolocation push to authorities + emergency contacts (WhatsApp/SMS).

Silent SOS (long press 2–3 seconds).

Offline first-aid guides.

Emergency console for authorities (map, status, reports).

4.5 Bilingual Communication & Support

Full bilingual UI.

Alerts for emergencies, weather, important notices.

Content management: events, POIs, news, campaigns, emergency messages.

Centralized QR management (type, location, status).

Executive reporting and exportable campaign/monthly reports.

5. Tourism Intelligence & Data Insights

Heatmaps by time/day + pre/post campaign comparison.

Anonymous demographics (language, origin, usage behavior).

Economic impact metrics (visits, coupon redemptions, route completions).

Executive dashboards (scans/day, unique visitors, top routes, SOS by area).

Integration with BI tools (Power BI, Tableau, Looker).

6. Data Model & Information Design

Core entities: User (pseudonymized), Device/Session, QR Scan, POI, Business, Event, Coupon/Reward, SOS Incident.
Principles: data minimization, aggregated reporting, 24-month retention + anonymization policies.

7. Security, Privacy & Compliance

Compliance with national data protection laws.

TLS 1.2+ encryption; encrypted storage for sensitive data.

RBAC; MFA for admin panels.

Audit logs (access, changes, downloads).

Daily backups, restoration tests, defined RPO/RTO.

Active security: pentesting, vulnerability monitoring/patching.

8. High-Demand Design (World Cup, Peak Seasons)

CDN for static content.

Auto-scaling for critical services (API, maps, SOS).

Load tests before peak seasons.

Fault tolerance via message queues (guaranteed logging of SOS and scans).

Automatic retry for network failures.

9. Deployment & Operations
Implementation Phases

Pilot

Zone-Based Expansion

Full City Rollout / High-Season Mode

Continuous Operations

Monitoring, updates, incident response, analytics reviews.

10. Smart City Evolution & Future Integrations

Public transport schedules, routes, stops; taxi/mobility app integrations.

IoT: foot traffic sensors, climate, noise, air quality.

Unified dashboards combining QR data + IoT.

Controlled public API for universities, business chambers, partners.

We need high quality, design, user-friendliness, and practicality. Show More
