Near Field Communication versus Bluetooth NFC technology
consumes little power when compared to standard Bluetooth
technology. Only when NFC has to power a passive, unpowered
source such as an NFC tag does it require more power than a
Bluetooth transmission. The close proximity that devices
connected using NFC must be to each other actually proves useful
in crowded locations to prevent interference caused when other
devices are present and trying to communicate. Bluetooth may
have trouble dealing with interference when trying to send
signals between two devices, especially when several other
devices are in close proximity. Another benefit of NFC
technology comes in its ease of use. Bluetooth requires users to
manually set up connections between smartphones and takes
several seconds. NFC connects automatically in a fraction of a
second, so fast it seems instantaneous. Though the users must be
close to one another to use NFC technology, it is faster and
easier to set up than a Bluetooth connection. Bluetooth do
