the idea of this project that i need to register with the app and you need to
register with the app ,and add funds to my account by Paypal or any other
payment method ,and then i can transfer money from my account to your
account only by sending my user id or by scanning your QR code so if a user
need to pay money to other user no need to send him his paypal account or
payment details .just by scanning QR code the money will be transferred from my
account to your account.
