Locked in a battle with Apple and Google, Samsung talked up the support it has gained from the financial community for its payment service on the first anniversary of its debut in the US.

Samsung Pay is supported by 500 banks, representing 80 per cent of the country’s debit and credit cards. The service launched a year ago with backing from just four banks.

Samsung is battling Apple Pay and Android Pay to gain traction with a range of partners led by financial institutions and retailers.

The South Korean vendor is also trying to open a new front through features such as in-app coupons, the storing and redeeming of coupons and a new cloud storage feature to restore membership, gift and Samsung Reward cards when a user signs into a new device.

In partnership with Quotient Technology, a digital promotions platform, Samsung Pay offers the ability to search, save and redeem coupons with select retailers directly within the app.
