What’s the difference between RFID and NFC? To be honest, that’s a really common question. RFID (radio frequency identification) and NFC (near field communication) are both wireless communication technologies that power the Internet of Things (IoT). The technologies can be used in everything from access control to asset tracking to payment.
RFID
Think of RFID as a one-way conversation: an unpowered RFID tag can provide information when scanned by a powered RFID reader, typically at distances between a few centimeters (high-frequency) and a few meters (ultra-high-frequency), and without the necessity of a direct line of sight. The tags themselves are available passive (meaning they must be powered by a separate device) or active (meaning they are powered and can transmit data). RFID is most commonly used in situations requiring asset tracking.
NFC
A subset of RFID, NFC does share some of the same properties – i.e., one-way communication without a direct line of sight – yet there are some d
