The fourth generation of the Delivery Information Acquisition Device, or DIAD IV, incorporates new radio communication links that allow it to communicate almost anywhere, anytime; dramatically expanded memory, and a color screen that allows alert messages to be color-coded for drivers.
The incorporation of three different types of radio communication links in each unit will ensure that package delivery information is available to customers almost instantaneously. The color screen will make life easier for drivers as well as customers signing for deliveries. Urgent customer pick-up messages, for example, can be color-coded to alert the driver. And the 128 megabytes of memory – 20 times that of the DIAD III – positions UPS to provide future features, like customer preference notes, to enable drivers to personalize service even more.
