Online payment transactions handled by Chinese payment service providers totaled 830 trillion yuan (about 134.3 trillion U.S. dollars) in 2012, according to an industry report published on Thursday. In 2012, banks handled 19.2 billion online payment transactions totaling 823 trillion yuan, according to a report published by the Payment & Clearing Association of China (PCAC). Another 10.46 billion online payment transactions amounting to 6.89 trillion yuan were handled by other payment agencies last year, the report said. Online transactions are being used not only in traditional areas, such as online shopping and bill-paying, but also in areas related to education, tourism, fund products, insurance, community services and medical and health services, the report said. But experts noted that the increasing variety of payment tools has also caused problems concerning the safety of funds and customer information, calling for strengthened regulation and supervision. \"The payment business is closely linked with people\'s daily lives, so customers will be less tolerant of risks,\" said PCAC\'s deputy secretary-general Kang Lin. The People\'s Bank of China, or the central bank, has so far approved 197 non-financial institutions to provide payment services, of which 72 are eligible for online payment business, tPCAC data showed. The association said mobile payments, or online payments made through mobile phones, totaling 2.31 trillion yuan were handled by banks in 2012, as well as 181.2 billion yuan in transactions handled by non-bank payment service providers.
