It looks fairly large (plenty of battery room), has no display (not sure about scanner battery usage), and transmits little data over WiFi per use. With it's simplicity, there's no reason they can't use the lowest power MCU and WiFi modules they can find.
All of these have good usability implications, but it looks like battery life was probably also a big design consideration.
