PayPal is an online payment service from the company PayPal (Europe) S.à r.l. & Cie, S.C.A, which offers a real-time payment solution.
To be able to use PayPal, you must have a PayPal account registered with your bank or credit card details, so that you don't have to enter this information every time you make a purchase.
With PayPal, all you need to do is enter your e-mail address and password, making it so easy to pay. Your PayPal account will be charged with the corresponding amount and you will receive a confirmation of payment via e-mail.
