In case you missed: Use your Android as a credit/debit card
It appears many android users missed the news that android pay was available in the UK. For a long time it was only available in USA but it was finally released to the UK.
How does it work?
First download and install android pay from the play store
Next add your bank card and accept terms and conditions.
Next look for the contactless payment symbol in shops. Where ever you see this symbol you can simply present your mobile to the card reader and it will process your payment using your mobile.
That’s it simple……..
