Support Google Wallet Question

http://androidforums.com – Does "Android Beam" have to be enabled for Wallet to work? I've tried using Wallet at my local gas station and it doesn't work. Although i dont sit there swiping back and forth looking like a moron but a quick swipe turns up nothing. NFC is enabled and Wallet is set up. Any way I can test this without testing it in public looking like a fool trying magic tricks over the credit machine? Also what is "NFC polling mode"? (General)
