(“APTG”) and a US-based carrier jointly completed Proof-of-Business (POB) mobile payment transactions enabled by the Cross-Carrier Payment System (CCPS) platform, a cross-carrier blockchain payment network developed by TBCASoft. The CCPS network aims to create the largest open payment network enabling cross-border transactions and interoperability for mobile payment solutions globally.


In the December 2019 POB, mobile subscribers from the US carrier visiting Taiwan used their mobile payment app to complete purchases at a participating merchant while on APTG’s payment network called Gt Pay, which is connected to the CCPS network. CCPS enables the transactions to be conveniently billed and paid through direct carrier billing in the purchaser’s home-currency.
