What is Near-field Communication?

What is Near-field Communication?

NFC is a wireless technology that makes use of interacting electromagnetic radio fields to transmit small bits of information between an “initiator” and a “target” — a key card and your hotel room door, for example.  This is the same technology that was hacked during Target’s breach, which is why it’s important to protect your company.

Technical Specifications: As with proximity card technology, near-field communication is mediated by magnetic induction between two loop antennas located within each other’s near field, effectively forming an air-core transformer.

The 3 near field communication operations modules are Peer-to-Peer, Read/Write Mode, and NFC Card Emulation Mode.  Peer-to-Peer is LLCP meaning it’s run by logical link control protocol.  Read/Write is RTD & NDEF, meaning Record Definition Type and Data Exchange Format.  NFC Card Emulation mode is a smart card capability for mobile devices.

NFC has a set-up time of less that .1 millisecond.  It’s range is up to 10 cm and it’s usability it high; it’s human-centric, easy, intuitive, and fast.  The selectivity is high given its security.  The use cases are: pay, get access share, initiate service, and easy setup.  The consumer experience is touch, wave, and connecting simply.
