Knowledge Base

Mini Lesson

1
Definition: NFC (Near Field Communication) is a short-range wireless technology that allows devices to communicate when placed very close together.
2
How it works: It uses electromagnetic induction between antennas to transmit data over very short distances (typically under 10 cm).
3
Why it matters: It enables secure and convenient contactless communication.
4
Real-world example: Contactless payments using smartphones or tapping access cards.
5
Key takeaway: NFC enables secure, short-range communication using electromagnetic induction.
