This informative whitepaper about Near-Field Communication examines the background, delves into the three modes of operation (read/writer, peer-to-peer, and card emulation) that will allow for the integration of NFC, and explores its various uses. More importantly, NFC security concerns are discussed, as well as the benefits offered by the technology.
