The total value of transactions via UnionPay bankcards totaled 32.3 trillion yuan ($5.3 trillion) in 2013, up 48 percent on 2012, according to data released by China UnionPay, the nation's top bankcard association.

The association said the transaction surge could be mainly attributed to increasing daily consumer spending in department stores, supermarkets and gas stations.

The number of businesses, POS (point of sales) machines as well as ATMs in China that accept UnionPay cards increased 58 percent, 49 percent and 24 percent, respectively, last year.

As of the end of 2013, UnionPay's services had covered 142 countries and regions, with over 11 million businesses and 1.1 million ATMs accepting UnionPay overseas.
