Citi Global Digital Payments head Barry Rodrigues said: “Whether it is online, on a phone, or at a store, we want Citi customers to have seamless, convenient and fast payment options wherever they go.

“With more than 100 million customers in the fastest-growing cities in 19 countries, Citi is uniquely positioned to accelerate payment innovation on a global scale. With Citi Pay, we are offering our customers flexibility wherever and whenever they choose to make purchases.”

Citi Pay will be made available to Citi customers for online and in-app purchases. As a digital extension of their current card relationship, Citi customers will be able to make online and in-app purchases using the same Citibank online user ID and password that they currently use to manage their existing online relationship with Citi.

Citi is partnering with Mastercard to leverage its digital payment service, Masterpass, to enable the online and in-app transactions. This will allow Citi customers to use Citi Pay at hundreds of thousands of merchants across 33 countries at launch.

For Android users, the digital wallet also enables Citi cardholders to make in-store purchases by tapping their Android mobile devices at any NFC-enabled point-of-sale terminal.

Later this year, Citi Pay will roll out to Citi customers in Singapore, Australia and Mexico with tap and pay capabilities. Citi Pay will also launch in the U.S. in early 2017, with online, in-app and tap and pay capabilities. Further Citi Pay launches in additional markets will follow.

Citi Pay is the latest digital payments announcement from the bank.

Earlier this year in the US, Citi joined Early Warning’s clearXchange network, which will enable Citi’s online and mobile banking customers to send or receive real-time person-to-person (P2P) payments to or from customers of participating network banks. Also in 2016, Citi enabled Samsung Pay for its card members in Singapore and Australia.
