What is NFC and is it safe?

Near-Field Communication lets two devices talk when almost touching — used for Apple Pay, transit cards, and tap-to-share. Its 4 cm range makes remote hacking impractical, and payments are tokenised so cards aren't exposed.

Follow-up questions

Should I turn NFC off?

You can leave it on. Real-world risk is very low.

Can NFC be cloned?

Payment tokens rotate per transaction, so no. Simple ID tags can be copied.
