What is paypal ? and how can be a member of that?

With PayPal, you have an online account that makes it easy to send money from a variety of sources (like your credit card or bank account) to a variety of recipients (such as an online store or your landlord) – without sharing your financial information. So the online store or your landlord never sees your credit card number or your banking information. See how PayPal helps you stay safe online. https://www.paypal.com/row/mrb/pal=GRTK7JMWB9VBU
