VII  PC Cards -- Pick A Card 1 IX  Chapter 1001: Summary

Before closing this chapter, a brief look at the possibilities presented by the Infrared Data Association (IrDA). This is a standard for transmitting data using infrared light, much like a remote control for home electronics.

If a notebook or PDA has an IrDA port, it can be used to transmit contact information between two PDAs or if a printer has an IrDA port, the ability to print almost automagically is given. Refer back to Chapter 0111 for a refresher on infrared.
