Can I place PayPal in a Frame or iFrame on my site?

PayPal allows its payment pages to appear inside a frame for only the following products:

Due to security concerns involving iFrame, the browser you use must be current and secure for iFrame use.

Transactions involving users of other browsers, or older versions of these browsers, shouldn't use the iFrame flow.

Note: If the PayPal iFrame becomes the source of an attack, the attack would appear to originate from the merchant site. Don't use the iFrame flow if you wish to avoid this additional risk.
