Visor is the trade name of a handheld computer manufactured by Handspring . The Visor is similar to the Palm computer and uses the Palm operating system ( Palm OS ). Data can be easily transferred between the Visor and other computers, including Palm handhelds, using HotSync technology. Interfacing is possible with Macintosh as well as with IBM-compatible desktop and notebook computers.
The Visor can be tailored to meet the needs of the individual user. It contains an expansion slot called Springboard that allows the addition of modules, each of which is designed for a specific function. The modules are plug-and-play and are hot-swappable (they are automatically recognized by the Visor, and they can be exchanged without powering-down or rebooting). Data can be stored and backed up with an optional flash memory module.
