BEIJING - The total number of bank cards issued by China's financial institutions reached 5.44 billion at the end of last year, putting average per capita bank card ownership at 3.99, latest data from the central bank showed on Tuesday.

Debit card issuance reached 5.1 billion and credit cards totaled 432 million, according to a report released by the People's Bank of China.
