Signing up for a PayPal account is straightforward: visit the PayPal website or download the PayPal app, choose the type of account (personal or business), and provide your email address, a secure password, and some basic personal information to get started.

To add money to your PayPal account, link a bank account to your PayPal account and use the "Add Money" option to transfer funds from the bank account to your PayPal balance. Alternatively, you can receive money from others in your PayPal account.

PayPal Credit is a reusable credit line offered by PayPal that can be used to make purchases online wherever PayPal is accepted. It allows users to make purchases now and pay over time. Approval is subject to credit authorisation by Synchrony Bank, and users can access special financing offers that vary depending on the merchant and purchase amount.

PayPal charges fees for receiving money for goods and services and for instant transfers to your bank account or card. Sending money to friends and family in the U.S. is free when using your PayPal balance or a bank account. Fees for international transactions and currency conversions apply according to PayPal's fee structure.

PayPal allows you to send money to anyone with an email address or mobile number. Once you're logged in, just enter the recipient's details, the amount, and send. To receive money, someone sends a payment to your email address or mobile number registered with PayPal, and the funds appear in your PayPal balance.
