Near Field Communication (NFC)
Here at barcode.com, we’ve mentioned near field communication, or NFC, a fair amount of times, but what exactly is it? Basically, Near Field Communication is a short-range, high-frequency form of wireless communication that enables data to be exchanged between devices approximately 4 inches apart. NFC is a simple extension of RFID that combines the interface of a smartcard and a reader into a single device. It is primarily used in mobile phones, but has also been popping up in other applications such as touchatag.
Both NFC and Bluetooth are forms of short-range communication technology that are integrated into mobile phones, however, NFC requires a shorter set-up time. Rather than performing manual configurations to identify Bluetooth devices, the connection between two NFC devices is established at under a tenth of a second. In addition, unlike Bluetooth, NFC is compatible with existing RFID structure and can work when one of the devices is not battery powered.
There seems to be a strong following of people who favor NFC to similar technologies. To learn more about NFC, you can visit the NFC forum here.
