In the video, the star of Seinfield is shown discovering Google Wallet and having the contents of his oversize wallets overflow into the streets.

Google Wallet, which has already been demonstrated to work on a Nexus S 4G to purchase pants from American Eagle, is hoped to introduce NFC payments to mainstream consumers. Google, who plans to have over half of all Android phones to be equipped with NFC, has partnered with big name brands such as macy’s, Subway, Walgreens, Toys R’ Us, and American Eagle in addition to over 100,000 other stores in the US to bring NFC nationwide.
