It’s only natural that people associate mobile technology with UPS. Why? Mainly because of the nifty handheld computers our drivers carry and ask you to sign when they’re delivering a package that requires your signature. At UPS we call them DIADs – short for Delivery Information Acquisition Devices.
What began more than 20 years ago as a bulky, brown clipboard with a monochrome screen has grown into a sleek, curvy, handheld computer with just about every wireless communications option known to man. You could call the DIAD the forefather of the smartphone.
