Braintree has begun offering its Venmo Touch mobile payments tool to banks, signing up Simple as the first partner to integrate the technology into its app.
Chicago-based Braintree's Venmo Touch stores users' card details so that they can pay with a single click for in-app purchases at partner merchants, including Hotel Tonight, TaskRabbit and Wrapp.
The firm is now pitching the technology to card issuers and mobile banking providers, arguing that integrating it into their own apps offers a route to the coveted 'top of wallet'.
The first player on board is digital banking platform Simple, which, over the next few weeks, will offer customers the option to opt in to Venmo Touch, which will turn on one touch purchasing across its network of apps.
Bill Ready, CEO, Braintree, says: "Simple is defining what the future of banking will be in a mobile world. With Venmo Touch, Simple is ensuring that their customers will have access to the absolute easiest way to pay on mobile devices."
