Google s Android Pay mobile payment system has launched in the UK, enabling users to make purchases using a smartphone.

The tap and go system lets users of Android smartphones – including those made by HTC, Samsung, Sony and Huawei – store a digital version of their debit or credit card on their device.

They pay for items by tapping it against a contactless card point, including in high street stores and on the London transport system.

Google has confirmed more banks will be added in the future.

An Android Pay app has been launched to help users set up and manage their transactions.

All transactions are encrypted for additional security, with specially generated digital tokens used instead of real card details when a purchase is made, to protect personal information.
