Update 5/18: Android Pay has officially launched in the UK. Coming soon to Australia and Singapore.
Update: As many have pointed out, the app is not yet in the Play Store. Google has since pulled the original tweet and commented that Android Pay in the UK is “not quite there yet”. An official announcement will likely coincide with I/O tomorrow.
After announcing plans for Android Pay’s first international expansion in March, Google’s contactless payment service is now available in the United Kingdom. According to the official Android Twitter account, those in the country can now download the app and set up the service.
