AT&T will soon start switching to an iPad-based point-of-sale system at its retail stores, 9to5Mac reports. Currently the carrier relies on desktop computers running software called OPUS, which handles sales tasks as well as checking inventory, corporate news, and customer upgrade status. In some regions the carrier has already tried to evolve by rolling out iPhones and tablets with scaled-back versions of OPUS; the iPhones, for instance, can only handle a few tasks like taking payments for accessories, or running basic account management.
