NFC Tags vs. RFID: Understanding the Differences
NFC (Near Field Communication) tags and RFID (Radio Frequency Identification) are both wireless communication technologies, but they serve different purposes. NFC tags are primarily used for short-range communication, typically up to 4 inches, making them ideal for contactless payments and data sharing between smartphones. RFID, on the other hand, can operate over longer distances, up to several meters, and is commonly used in inventory management and access control. While both technologies use radio waves, NFC is a subset of RFID, offering more secure, peer-to-peer communication, whereas RFID is better suited for bulk data transfer and tracking.
