Explanation

NFC (Near Field Communication) operates at extremely short range (typically under 4 cm) and is most widely recognized for enabling contactless payments such as Apple Pay, Google Pay, and tap-to-pay credit/debit cards. IoT devices typically use Wi-Fi, Zigbee, Z-Wave, or Bluetooth rather than NFC. Inventory tracking at scale uses RFID (which operates at longer ranges) rather than NFC. Tethering uses Bluetooth or Wi-Fi to share an internet connection between devices. NFC's very short range makes it ideal for secure, intentional transactions like payments, access badges, and small data exchanges.
