Near-field communication
A useful mental model for the technology shaping daily life.
The useful idea
- The useful idea
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1+1⁄2 in) or less.
- How it works
NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections.
- Why it matters
Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on an NFC-enabled device such as a smartphone.
Why this matters
Use Near-field communication as a lens when judging what a digital tool can — and cannot — do.
