NFC
What is NFC?
Near Field Communication or NFC, is a short-range (about a
10 centimeter, around 4 inches) wireless connectivity
technology standard designed for intuitive, simple and safe
communication between electronic devices. Applications of
NFC technology include contactless transactions such as
payment and transit ticketing, simple and fast data transfers
including electronic business cards and access to online
digital content.
How does NFC work?
NFC is based on contactless and Radio Frequency
Identification (RFID) solutions, which consist of a TAG and a
reader. The reader, when activated, emits a short-range
radio signal that powers up a microchip on the TAG, and
allows for reading a small amount of data that can be stored
on the TAG. NFC is different from other contactless or RFID
technologies in that it has a very short operating distance.
When the user shares to the TAG, his/her device reads the
content of the TAG and executes it into action. The user only
accepts the execution, eg opening a web page, calling a
favorite number, or sending an SMS.

-
type1: Topaz
®
.
