London - Alphabet’s Google unit said on Wednesday its one-touch payment app for Android devices, Android Pay, will be launching in the UK in the next few months.

Android Pay will support MasterCard and Visa credit and debit cards issued by UK banks such as Bank of Scotland, HSBC, Lloyds Bank and M&S Bank, the company said in a blog post.

Commuters travelling around London will be able to pay using the app on the city's buses, trains and the London Underground, Google said.
