Driven in part by pressure for contactless interactions during the pandemic, technology is rapidly evolving in the travel industry. The latest developments include major hotel brands enabling guests to add digital room keys or unlock rooms through their smart devices. Virtual queues can reduce your time waiting in line.

And robots have started making food deliveries, too.
