Paypal is part of the EBAY group and was invented for safe payment on EBAY. Now a lot of other websites offer payment with it too. You can sign up on www.paypal.com. You register an account with your e-mail address and enter the info for at least one of your bank accounts. Then you can transfer money just by sending it to someone elses e-mail addess. Its safe because the other person involved never gets a hold of your bank account info. After you sent the money it will be booked (by paypal) from your account or you can transfer it from your bank account to the paypal bank account with a special reference number. Whatever you chose at first.
