We use PayPal at www.PayPal.com to process our
online transactions. The security of your information, transactions,
and money is the core of PayPal's business and a top priority.
PayPal automatically encrypts your confidential
information in transit from your computer to PayPal's using the
Secure Sockets Layer protocol (SSL) with an encryption key length
of 128-bits (the highest level commercially available). Before you
even register or log in to PayPal's site, PayPal's server checks
that you're using an approved browser - one that uses SSL 3.0 or
Once your information reaches PayPal, it resides
on a server that is heavily guarded both physically and electronically.
PayPal's servers sit behind an electronic firewall and are not directly
connected to the Internet, so your private information is available
only to authorized computers.
You do not need an account through PayPal to send
a payment. If you are new to PayPal you will simply go through an
alternate checkout, and will have the option to sign up with PayPal
afterwards. If you have a PayPal account, you will log in when prompted
to complete your online transaction.
