Darshan booking sequence: the devotee logs in with mobile OTP, chooses a date and time slot and enters the ID (Aadhaar last digits) of each person. The booking service checks the per-ID monthly limit and holds the slots for 10 minutes. The devotee pays by UPI. On success the booking is confirmed and a QR ticket is sent by SMS and email. At the temple the QR code is scanned at the gate and ID is checked.
