(Yicai Global) Sept. 27 -- Nets Union Clearing Corp.'s platform for integrating various payment institutions recently initiated a combined stress test after running for nearly 6 months. Several banks and payment services participated.

Nets Union, Industrial and Commercial Bank of China Ltd., other major banks, Alipay and other high-volume domestic payment service operators conducted the test from 3.00 a.m. to 6.00 a.m. yesterday

Three rounds of testing showed that Nets Union's stress peak exceeds 20,000 TPS (transactions per second), while that of Nets Union and its directly connected channels is more than 35,000 TPS.

Each commercial bank in the test targeted at least 50 percent of the transaction value of the largest online shopping day in the world -- Singles' Day (Nov. 11), Nets Union said.

Nets Union aims to maintain a stable capacity of 120,000 TPS, and to achieve a capacity of 180,000 TPS in peak intervals.

Payment institutions set up the Nets Union platform (the Online Payment and Clearing Platform of Non-Banking Payment Institutions) under the guidance of the central bank and the organization of the Payment and Clearing Association of China on the principle of "co-constructing, co-holding and sharing."

It aims to provide unified and public capital clearing services for payment institutions and streamline business between such institutions and banks.

The central bank is mandating that Nets Union handle all online business dealings conducted by payment institutions linked to bank accounts from June 30 next year.
