Toss Information Between Phones, But Be Careful

Over the years there has been many different ways to transfer information between mobile devices. In the Pocket PC days we used infrared to beam information between two Pocket PCs, and because infrared requires line of sight, the two devices had to be perfectly aligned with each other. Next came Bluetooth, which provides a wireless way to transfer information between devices, but requires that both have the same Bluetooth profiles, be turned on, and configured to send and receive information.
