Android pay is very important. I've been watching and writing about Wallet/mobile payments for several years (see my guest post here http://kenmccarthy.com/blog/mobile-google-gets-it). Apple pay only affirms the method more.

Mobile click costs are down, cannibalising pc search ad revenues, and hitting Google's bottom line. They have a slew of recent announcements (see May Livestream event) all focusing on and pitching mobile in an effort to bid the value of the medium up.

Anything which helps close the loop between paid ad clicks on mobile and return on mobile ad spend from offline / in store sales will make it more competitive between those advertisers who know what they are doing and following the money.
