Overview

• The 'N' icon in the Android status bar signifies that NFC (Near Field Communication) is enabled on the device.
• NFC allows secure, short-range data exchange over a few centimeters, commonly used for mobile payments, device pairing, and file transfers.
• While NFC is always active on iPhones without a visible indicator, Android devices vary in how the 'N' symbol is displayed depending on the manufacturer.
• The technology is highly energy-efficient and does not significantly impact battery life, activating only when in use.
• Users are advised to avoid scanning unknown NFC tags in public spaces to prevent potential security risks.
