Smart One Page Checkout Credit Card field fills with "undefined" in Internet Explorer

When attempting to checkout in the Smart One Page Checkout (SOPC) in Internet Explorer, the credit card field fills with "undefined" and does not allow the purchase to continue.

This is caused by forcing IE7 emulation in your site template.master file in the head section.

Replace references to: content="IE=EmulateIE7" with content="IE=edge"
