NFC technology is a fast, secure way of wireless communication as data is transferred within close proximity. The frequency range for transmission is around 13.5 MHz and data can be transferred at a maximum of 425 kilobits per second speed. That is pretty fast enough to send a few photos or text files.
In order to transfer data using NFC, the two devices should be at a range of 10cm max. NFC pairing of two devices is pretty quick when compared to “searching for a device” method found in Bluetooth technology.
