Stay on Track GPS-equipped cell phones are the latest way to keep tabs on mobile employees.

If you could check on the location of your employees, would you? GPS-equipped cell phones make that possible--and they're more affordable than fixed GPS systems. Nextelis the main provider, but expect other carriers to get onboard this year.

Brian Gratch, principal at wireless consulting firm Gratch Associates in Evanston, Illinois, refers to these capabilities as "track and trace." Growing businesses with delivery drivers or workers in the field will find this technology appealing. "The attraction for small businesses is in productivity, cost control, the ability to optimize a route, and accountability," says Gratch.

That latter attraction is particularly important. GPS-enabled phones can help businesses keep track of mileage for tax purposes and verify employees are where they're supposed to be. But employees may feel like Big Brother is watching. Gratch recommends that you carefully spell out why you're using the devices and how they work. Employees should know when they're being tracked.
