Following its launch last week of a wallet app, China Unionpay has kept up momentum with the debut of a smartphone accessory that enables consumers to check account balances and make payments, according to People’s Daily.

Consumers with an iOS or Android smartphone can attach China Unionpay’s device and then swipe cards to check the balance of their debit accounts, as well as pay credit cards and utility bills.

They can also use the device, which is called Colorful, to make real-time transfers between China Unionpay-based debit cards. Rivals payment providers such as Alipay or Tenpay typically take at least one working day to handle such a transfer.

The device is available online but will be offered in traditional retail channels later.
