Both technologies have been associated with each other but they differ with regards to technology and application. Beacons transmit signals to other smart devices through Bluetooth in a defined proximity while an NFC is a short-range communication technology that works in the range of small centimeters. NFC's usually require a tap or touch to establish contact, like a bankcard reader and a smartphone when performing a contactless payment transaction.
