PayPal parent eBay says it is buying online and mobile payments technology provider Braintree for $800 million in cash.
Braintree's payments technology is used by popular start-ups such as vacation rentals siteAirbnb, cab-hailing app Uber and restaurant reservations site OpenTable.
The move comes as eBay's PayPal unit works to evolve from its roots as an online payments provider, expanding its offline, mobile and online offerings to stores, restaurants and other business.
San Jose, California-based eBay says that it will operate Braintree as a separate business. Bill Ready, the CEO of the Chicago-based company, will report to PayPal President David Marcus.
Braintree's roughly 200 employees are staying with the Chicago-based company.
EBay says it expects to close the deal before the end of the year.
