PayPal is an online payment platform that allows users to send and receive money, make purchases, and manage transactions securely through a connected bank account, credit card, or debit card. It functions as a trusted intermediary between buyers and sellers, keeping financial details private during transactions. Users create an account, link it to their financial sources, and can then send money to others via email or phone number, or use PayPal as a payment option on many online retail websites. PayPal transactions are typically completed quickly, and the platform also offers services for businesses like payment portals, invoicing, and financing options. It is widely accepted by millions of retailers globally for online and in-person payments.

How PayPal works:

• Users sign up with an email address and link a bank account, credit card, or debit card.
• When making an online purchase, users select PayPal as the payment option and authorize the payment without sharing their financial information with the merchant.
• PayPal transfers funds between users or from users to businesses securely.
• It also allows sending money directly using an email or mobile number linked to a PayPal account.
• For sellers or businesses, PayPal provides tools for managing payments, invoicing, and facilitating transactions in-store or online.
• PayPal enhances security by acting as an intermediate, protecting users' financial privacy and providing fraud monitoring.

In summary, PayPal is a secure payment system that works by connecting users' bank accounts or cards to enable easy, fast, and private online money transfers and payments. It supports both personal and business uses globally.
