PayPal is a global e-commerce business allowing payments and transfers to be made through the Internet. Online transfers serve as electronic alternatives to paying with traditional paper methods, such as checks and orders. PayPal is an acquirer, performing payment processing for online vendors, auction sites, and other commercial users, for which it charges a fee. It may also charge a fee for receiving, proportional to the amount received. The fees depend on the currency used, the payment option used, the country of the sender, the country of the recipient, the amount sent and the recipient’s account type. In addition, eBay purchases made by credit card through PayPal may incur extra fees if the buyer and seller use different currencies.
