Hi
@takuzha. I'm not sure how you'd do that. If I open Google Wallet, it says it doesn't meet the security requirements.
However, I wouldn't suggest you try to work around this by forcing Google Pay to work in the beta release. You may be contravening the agreement you have with your bank if you run contactless payment software in an unsupported configuration or on a rooted platform.
As I say, the Samsung Pay/Wallet is an effortless alternative that works and is supported by a wide number of UK banks.
I don't think I'll go back to Google Pay but please feel free to give it a try and form your own opinion on if it meets your needs in the way Google Pay does.
