Fitbit has launched the Fitbit Versa 2, a next generation enhancement of its Versa smartwatch line, which now includes Amazon Alexa voice command technology, a Spotify streaming music app and Fitbit Pay built into all new models of the device. 

The watch is also packed with several new health and fitness features, including Sleep Score and smart wake, as well as other features to measure heart rate and enhancements to measure oxygen levels during sleep. 

"At Fitbit we believe that health belongs to everyone and that people should not be priced out of having access to devices and features that can help them improve their health," James Park, co-founder and CEO of Fitbit, said in a company release. 

The Fitbit Pay technology will allow users to make secure payments without a mobile phone and without the need to pull out a credit or debit card. The smartwatch also works in four major public transit systems that use tap-to-pay, including the New York City OMNY pilot, TransLink in Vancouver, Transport for London and Taiwan iPass. 

Versa 2 is currently available for presale at Fitbit.com and select online retailers at $199.95, in black with a carbon case. The watch will be available in retail stores starting Sept. 15, including Walmart, Amazon, Best Buy, Kohl's, Macy's, Target and Verizon.
