Amazon ordered digital timers, whiteboards and digital cameras for its digital real-estate division, the Wall Street Journal reported.

The orders represent the latest step in Amazon’s quest to tap into digital technology, which could help it increase its revenue and expand into the lucrative real estate market.

Amazon’s real estate division, which includes digital businesses such as real-time pricing and scheduling, is estimated to be worth $1.4 billion in revenue.

The company previously announced that it had launched a $1 billion fund to invest in digital businesses.
