How do I set up a mobile ticketing app for presales, priority access, and mobile wallet barcode entry?

To set up a mobile ticketing app for presales, priority access, and mobile wallet barcode entry, you’ll want to design it in three layers:

1. Ticketing rules and access control
2. Mobile app + backend infrastructure
3. Wallet/barcode presentation and scanning

Here’s a practical setup roadmap.

---

1) Define the ticketing flows

Presales

Use presales to sell tickets before the public on-sale date.

You’ll need:

• Event inventory with sale start/end windows
• Customer eligibility rules
• Promo codes or access codes
• Limits per user/account/card/device

Common presale types:

• Artist presale
• Fan club presale
• Venue presale
• Credit card presale
• VIP / invite-only presale

Priority access

Priority access usually means letting certain users enter a queue or unlock inventory before others.

Implement:

• User tiers or membership status
• Time-based access windows
• Whitelist/allowlist logic
• Queue management for high-demand drops

Mobile wallet barcode entry

This lets users add tickets to:

• Apple Wallet
• Google Wallet

The wallet pass should contain:

• Event name
• Seat/section
• Date/time
• Unique barcode or QR code
• A live status / anti-fraud token if supported

---

2) Choose your ticketing architecture

Option A: Use a ticketing platform API

Fastest path. Use an existing provider that supports:

• Presales and promo codes
• Mobile tickets
• Wallet passes
• Entry scanning

Examples of capabilities to look for:

• Event management API
• Barcode generation
• Wallet pass creation
• Transfer/resale controls
• Check-in validation

Option B: Build your own ticketing system

If you need full control, build:

• Admin portal
• User app
• Ticket inventory service
• Authentication and entitlement service
• Wallet pass service
• Scanner app

This is more work, but best if you need custom rules.

---

3) Core backend components

A. Authentication and user profiles

Support:

• Email/password
• Social login
• OTP login
• Membership tiers
• Verified identity if needed

Store:

• User ID
• Eligibility status
• Purchase history
• Device tokens
• Wallet pass IDs

B. Presale/priority eligibility service

This service checks whether a user can access a sale.

Examples of checks:

• Is the user on the presale list?
• Has the user entered a valid access code?
• Is the sale window active?
• Has the user exceeded ticket limits?

C. Inventory and order service

Tracks:

• Total tickets
• Reserved tickets
• Sold tickets
• Hold times for checkout
• Seat assignments if reserved seating

D. Ticket issuance service

After purchase:

• Generate unique ticket ID
• Assign barcode/QR code
• Create wallet pass
• Send confirmation email/push

E. Validation/scanning service

At the venue, scanner app should:

• Read barcode/QR
• Call backend to validate ticket
• Mark ticket as used
• Reject duplicates or invalid tickets
• Work with offline fallback if necessary

---

4) Wallet pass setup

Apple Wallet

You’ll need:

• Apple Developer account
• Pass Type ID
• Signing certificate
• PassKit-generated .pkpass file

Pass should include:

• Ticket metadata
• Barcode/QR
• Event details
• Relevant dates and locations
• Optional NFC or dynamic fields, if supported

Google Wallet

You’ll need:

• Google Wallet issuer account
• JWT or API integration
• Object and class definitions for event tickets

Include:

• Ticket object
• Barcode/QR
• Event info
• User name
• Seat assignment

Barcode format

Use one of:

• QR code for stronger scan reliability and more data
• PDF417 if your scanner system supports it
• Code 128 for simpler linear scanning

For mobile ticketing, QR is usually easiest.

---

5) Presale and priority access implementation

Access codes

Generate:

• Unique single-use codes
• Multi-use codes with limits
• Time-bounded codes

Examples:

• FANCLUB2026
• Unique token per user: X9K2-7QPL-4MND

Queue and inventory release

If demand is high:

• Put users in a virtual queue
• Release inventory in batches
• Use per-user reservation timers
• Expire carts after a short window, like 5–10 minutes

Segmentation rules

Priority access can be based on:

• Membership level
• Past purchases
• Geography
• Subscription status
• Verified fan status

---

6) Mobile app features

Customer app

Should include:

• Login/signup
• Upcoming events
• Presale unlock entry
• Ticket purchase flow
• Wallet pass download
• Ticket history
• Transfer/share options
• Push notifications

Scanner app

Should include:

• Camera scanning
• Instant validity response
• Event selection
• Offline mode with cached lists
• Fraud alerts
• Audit logs

---

7) Security and anti-fraud

Important protections:

• Encrypt ticket tokens
• Use signed barcodes or rotating tokens
• Prevent screenshot reuse with dynamic validation where possible
• Rate-limit access code attempts
• Log device/IP suspicious behavior
• Make tickets non-replayable after check-in
• Support ticket transfer rules carefully

If using wallet passes:

• Use server-side validation at scan time
• Avoid embedding sensitive data directly in the barcode payload

---

8) Notifications and user communication

Send:

• Presale opens soon
• Priority access granted
• Ticket purchase confirmation
• Wallet pass ready
• Event reminder
• Gate/check-in instructions

Use:

• Email
• SMS
• Push notifications
• In-app banners

---

9) Testing checklist

Test these cases:

• Valid presale access
• Invalid/expired access code
• Ticket limit exceeded
• Inventory sold out
• Wallet pass installation on iOS/Android
• Barcode scanning speed and accuracy
• Duplicate scan rejection
• Offline scan fallback
• Ticket transfer and re-issue

---

10) Suggested implementation stack

A common modern stack:

Mobile app

• Flutter or React Native for cross-platform
• Native iOS/Android modules for Wallet integration if needed

Backend

• Node.js / NestJS, Java / Spring, or Python / FastAPI
• PostgreSQL for orders/tickets
• Redis for queues and reservation timers
• Object storage for pass files
• Message queue for notifications

Scanner app

• Native Android/iOS or tablet web app
• Camera SDK for QR scanning

---

11) Recommended rollout plan

1. Launch basic ticket purchase
2. Add presale codes
3. Add membership-based priority access
4. Add Apple Wallet and Google Wallet passes
5. Add scanner app and venue validation
6. Add transfer, refunds, and resale controls
7. Add dynamic/rotating codes for higher security

---

12) If you want the quickest path

If you need to get live fast:

• Use a ticketing provider with API support
• Integrate presale access codes and membership logic
• Enable mobile wallet passes
• Use their scanning/validation tools where possible
