Switch wallet pass barcodes from QR to Code 128 format using the card_number (digits only), so standard retail barcode scanners can read loyalty cards. Apple Wallet keeps QR as fallback in barcodes array. Also fix stale Vendor.loyalty_program relationship (now company-based), add parent init calls in vendor JS components, and update module docs to reflect Phase 2 completion.

Anti-Fraud System
Staff PIN Verification
All stamp and points operations require staff PIN verification (configurable per program).
# PIN is hashed with bcrypt
pin.set_pin("1234") # Stores bcrypt hash
pin.verify_pin("1234") # Returns True/False
Lockout Protection
- Max failed attempts: 5 (configurable)
- Lockout duration: 30 minutes (configurable)
- After lockout expires, PIN can be used again
- Admin can manually unlock via API
Cooldown Period
Prevents rapid stamp collection (fraud prevention):
Customer scans card → Gets stamp → Must wait 15 minutes → Can get next stamp
Daily Limits
Maximum stamps per card per day (default: 5).
Wallet Integration
Google Wallet
Architecture: Server-side storage with API updates
- Program created → Create
LoyaltyClassvia Google API - Customer enrolls → Create
LoyaltyObjectvia Google API - Stamp/points change →
PATCHthe object - Generate JWT for "Add to Wallet" button
No device registration needed - Google syncs automatically.
Apple Wallet
Architecture: Push notification model
- Customer adds pass → Device registers with our server
- Stamp/points change → Send push notification to APNs
- Device receives push → Fetches updated pass from our server
Requires apple_device_registrations table for push tokens.
