Want to develop an web application to get customer details for visa application form, with OTP verification integration and Payment gateway integration and then send a confirmation Mail with PDF attachment with a booking ID.
This is part of a project, hence it must be easy to merge with the mail project - like the bookings will be taken to a admin dashboard after above job.
This requirement can be developed using asp.net c# with sal or mysql as backend. Payment and otp verification can be developed using any paid gateways. Free gateways will be insecure.
