The SwitchBack-PC brings the power of the desktop to a portable, rugged, handheld solution in just three pounds. The SwitchBack can withstand extreme shock and vibration, moisture, heat and cold. The SwitchBack has all the features of a rugged tablet PC, but it's smaller, more powerful and it has a custom defined "BackPack" Module to the back of the computer. Law enforcement agencies can customize SwitchBack Modules. Examples include: Routine Stop Module - Package a barcode scanner (as found on a driver's license) along with a digital camera for license plate verification. Issue and print tickets on the scene. Include a biometric fingerprint reader to automatically pull up criminal records and mug shots without calling back to the station; or Breathalyzer Module - Integrate a breathalyzer to allow officers to conduct roadside alcohol testing and process the results using the SwitchBack.
