NFC (Near Field Communication) is a wireless technology that
allows short-range communication between compatible devices.
It is commonly used in contactless payments, smart cards, and
data sharing.
NFC works by using electromagnetic fields to enable
communication between two NFC-enabled devices when they are
close (usually within 4 cm). It does not require an internet
connection to function.
NFC is used in contactless payments (Google Pay, Apple Pay),
public transport cards, keyless entry systems, digital
business cards, and smart posters for marketing.
Yes, NFC is secure because of its short-range communication
and encryption protocols. However, users should always be
cautious when making payments and ensure their device has
security measures enabled.
No, not all phones have NFC. Most modern smartphones,
especially Android and iPhones, come with NFC functionality,
but it's best to check your device's specifications to
confirm.
