Apple Pay just completed a quadrilogy of major credit card support.
Starting this fall, Apple Pay's major CC support count will be up to four when Discover joins Visa, MasterCard and American Express in facilitating contactless payments at participating locations.
Apple Pay also works for buying apps on the iPad Air 2 and iPad mini 3. For those concerned about their card numbers being stored on their device or in the cloud, Apple Pay relies on a system that generates a one-time security code for transactions, with no numbers stored for hackers to get their mitts on.
With the addition of Discover, Apple Pay moves further to cementing its place as a legit mobile payment option. The service is rumored to expand beyond the US into Canada sometime this year, though no official word has been released on that.
