PayPal is a secure, encrypted software service that allows you to make financial transfers, such as buying products from on-line stores and auctions. A basic PayPal account is free. If you just plan to use PayPal for the occasional eBay auction or online purchase or charity contribution, a personal account is the right choice.
You can send funds to anyone with an e-mail address, whether or not they have a PayPal account. Funds transferred via PayPal reside in a PayPal account until the holder of the funds retrieves them or spends them. If you intend to use PayPal to accept payments for your own business, then a business or premier account would be more suitable. If you select a personal account, you can upgrade in the future.
