PayPal Payments Overview
This section provides a brief overview of each of the products described in this manual.
PayPal Account Optional
With PayPal Account Optional turned on, your customers who are new to PayPal will be able
to make credit card payments without signing up for a PayPal account. This setting is available
from your Profile, and is available to Premier and Business accounts.
PayPal Account Optional is turned on by default for all U.S. Premier and Business accounts.
This means that your customers who already have PayPal accounts will go through the same
Website Payments experience to which they’re accustomed.
Your new customers, or existing customers who are new to PayPal, will go through a checkout
that doesn’t require PayPal signup; however, they will have that option available after
completing the payment. Whether customers sign up for a PayPal account or not, you can set
your Buy Now, Donations, and Shopping Cart Buttons to return them to your website, and you
will still receive the same notification emails as in the current checkout flow.
For more information about PayPal Account Optional, see Chapter 4, “PayPal Account
Optional.”
Buy Now and Donations Buttons
PayPal makes it easy to accept donations and payments for single items through your own
website. The Buy Now and Donations Buttons feature can be implemented in minutes, giving
you easy access to business from PayPal’s millions of members, and any other buyer on the
Web.
Because using Buy Now and Donations Buttons to send and receive payments is secure, both
you and your customers remain protected. PayPal automatically encrypts your confidential
information using the Secure Sockets Layer (SSL) protocol with an encryption key length of
128 bits (the highest level commercially available). Your customers will not need to share
their private financial information (e.g. credit card or bank account numbers) during the
transaction, so they can complete payment while retaining security. However, using button
encryption does impose some limitations, and therefore PayPal does offer both encrypted and
unencrypted button options.
The flexibility of our Buy Now Buttons feature will keep your website working for you. You
can accept payments from current PayPal members as well as people who have just signed up
for our service, and you won’t lose your customers after they have made a purchase—the
payment process lets you return buyers to your website, not lose them to ours.
