Alphabet decided to update and re-brand the service last September after Apple launched Apple Pay in 2014 with a stronger business model due to some key alliances with banks.
Android Pay's launch in the UK will arrive with support for Visa or MasterCard debit or credit cards from a variety of supported banks including Bank of Scotland, First Direct, Halifax, HSBC, Lloyds Bank, M Bank, MBNA, and Nationwide Building Society.
Barclays said earlier this week that it is not planning on participating in Android Pay in the UK.
Google is promising that businesses that already have contactless terminals need do nothing to accept payments from Android Pay.
Finally, Android Pay will be launching a deal-focused program called Android Pay Day that will be exclusive to the UK, at least initially.
To encourage sign-ups and continued use of the service, which already has quite a lot of competition in the mobile and contactless payment world, a new deal will be posted the week before pay day every month.
