Status changes to active when you scan your QR code at the entrance. Parking session begins.

If you don’t show up within 30 minutes of your reservation time, the system automatically cancels and applies a penalty.

Common Issues

Error: “Saldo Insuficiente”Solution: You need at least 120 credits to make a reservation. Go to Payment Methods to recharge your balance.
Error: “Lugar ocupado”Solution: The spot was reserved by another user while you were completing your reservation. Go back and select a different spot. The system uses Firestore transactions to prevent double-booking.
Issue: Verification code not in inboxSolution:
  • Check your spam/junk folder
  • Wait up to 2 minutes for delivery
  • Ensure your email is correctly registered in your profile
  • Try canceling and restarting the reservation
Error: “NIP Incorrecto”Solution: Double-check your security NIP. If you’ve forgotten it, go to Settings > Security to reset your NIP.

Technical Details

​
Minimum Balance Requirement

The system requires a minimum balance to ensure you can complete your parking session:
Source Reference
const SALDO_MINIMO = 120; // Minimum 120 credits required

if (currentCredits < SALDO_MINIMO) { 
  Alert.alert("Saldo Insuficiente"); 
  return; 
}

​
Reservation ID Format

Each reservation gets a unique ID for tracking: 
const safeDate = displayDate.replace(/\//g, '-'); 
const reservationID = `${safeDate}_${displayTime}_Spot${selectedSpot}`;
// Example: "04-03-2026_02:30PM_Spot12"

​
QR Code Data

Your ticket contains encoded reservation data: 
const qrDataEncoded = encodeURIComponent(reservationID);
// This QR code is scanned at entrance/exit gates
