Since you will be using your device on the road, there is an increased likelihood of the device being misplaced or stolen. This might result in confidential business information becoming available to the person with the device. As a security measure, you should set up a passcode that needs to be entered before anyone can access the apps and information on your device. You should also configure your device so that you can remotely locate the device or even remotely wipe the device if it is ever lost. Remote locating and wiping is a feature that is available for any Apple device via the ‘Find My iPhone’ app. Full instructions on how to set it up are available on the Apple website:
