NFC in plain language
Near Field Communication, usually shortened to NFC, is a short-range wireless technology. It allows compatible devices or a device and a small NFC tag to communicate when they are very close.
An NFC tag can hold a destination such as a web address. Tapping a compatible phone can then offer to open that destination.
How NFC sharing works for business cards
A smart business card can contain an NFC tag linked to a public digital profile. The physical card creates the moment of interaction; the profile holds the information and actions that may change over time.
- The recipient normally does not need a dedicated app
- The linked profile can remain current
- A QR code can provide a useful alternative
Practical considerations
Phone support, device settings, tag placement, and the quality of the destination all affect the experience. Always make the tap area clear and provide another sharing method when needed.
