How Near Field Communication Works

Author's Note

I've been interested in NFC technology since I first heard about it being used in Japan. At the time, even the idea of a smartphone was exotic. Now it seems like smartphones are the new standard, and it surprises me we haven't moved toward an NFC-based transaction system yet. Part of the problem may be that different financial institutions want to establish their own payment standards and retail organizations must choose which ones to support. It could be a few more years before we see this tech rolled out into our neighborhood stores.
