Bluetooth uses radio frequencies, infrared uses light.
With IR, you need line of sight, bluetooth just needs to be in range.
Otherwise the function they perform (short range wireless device communication) is similar

Unlike infrared, Bluetooth isn't a line of sight and
it provides ranges of up to 100 meters. Bluetooth
is also low power and low processing with an
overhead protocol. What this means, is that it's
ideal for integration into small battery powered
devices. To put it short, the applications with
Bluetooth are virtually endless.
Bluetooth has several positive features and one
would be extremely hard pressed to find downsides
when given the current competition. The only real
downsides are the data rate and security. Infrared
can have data rates of up to 4 MBps, which provides
very fast rates for data transfer, while Bluetooth
only offers 1 MBps.
For this very reason, infrared has yet to be
dispensed with completely and is considered by
many to be the complimentary technology to that
of Bluetooth. Infrared has inherent security due
to its line of sight.

bluetooth firstly is a rather new technology. Infrared is a bit older. Bluetooth sends data and files wirelessly to another device that has connected through bluetooth signals. Infrared basically does the same thing except you need to send an infrared signal directed to the other device's infrared reciever port. A website like this http://developers.sun.com/techtopics/mobility/midp/articles/bluetooth1/ may help. You can just Google "Bluetooth vs. Infrared"

Bluetooth is a technologies offering instant very own area networks (WPANs) for small instruments as cellular telephones or PDAs. It operates on the unlicensed 2.4-GHz business-medical-scientific (ISM) band, and has truly been well-known with the help of Ericsson. The Bluetooth specific pastime team (SIG) replace into then based with its unique promoters being Nokia, IBM, Intel, and Toshiba. immediately, approximately 2000 individuals are counted, among them Agere, 3Com, Lucent, and Microsoft. The call "Bluetooth" replace into chosen of the Denish King Harald Bluetooth. The complementary of Bluetooth is the Infrared gadget of the Infrared archives association (IrDA). throughout the time of the previous couple of months, this is been argued that Bluetooth has been created rather for Infrared. although, that may no longer particularly genuine: Bluetooth has been invented as an enhancement of Infrared, exceedingly in terms of low fee, small quantity, low ability, and the accomplishment of Infrared's barriers, such because of the fact the its unidirectional connections, the connectivity selection of in elementary terms meter or its project to point-to-factor connections. besides the fact that if Bluetooth has rather coped with those constraints, e.g. with the help of omnidirectional connections, the connectivity selection of as much as ten meters, or its ability for factor-to-multipoint connections, the two technologies are particularly complementary. whilst Bluetooth is particularly applicative for networking, Infrared is greater suited to the direct connections, e.g. for replacing business enterprise enjoying cards.

the difference is that infrared is a bit older technology which allows u to exchange data but it is very close range and u must face each other...bluetooth on the other hand is newer with more capabilities especially on cell phones....and it has range of up to 30 feet and you dont have to be in clear view to exchange data with someone else cuz it can even go through walls unlike infrared...

Bluetooth: uses radio waves to transfer data, has longer range and speed and is omni directinoal-can happen any direction.
IR: uses infra red light light being the most iportant word, does not use radio waves uses light waves just out of the visible spectrum, is shorter range and speed and older and only works when pointing the transmitters together.

bluetooth is a wireless protocol and infrared is, well, infrared.
So the choice is wireless (Not WiFi) or light!
