Paypal 101
PayPal is the world's most popular "middleman service" for online purchasing. Where moneygrams and wire transfers were the standard in the 20th century, today over 99 million Internet users prefer to use PayPal to send money to each other via email. PayPal has become such a convenient and trusted way to transfer money online, 95% of eBay's purchases go through PayPal.
How PayPal Works.
As an online financial transaction broker, PayPal lets people send money to each other's email addresses. At no time will either party see the other's credit card or bank information.
Similar to an escrow service, PayPal acts as the middleman holder of money. Through its policies, practices, and business integrity, PayPal has earned the trust of both parties. With multiple guarantees in place, buyers and sellers entrust PayPal with their credit card and bank information. PayPal keeps that private customer information secret. Then, while "blinded" from the other party's confidential information, strangers safely send money to each other through PayPal and email.
