Xinda Financial's UnionPay Front-end System

The UnionPay Front-end System is a crucial component of various banking systems, responsible for handling all interbank transactions. It enables interconnection of bank card transactions through the UnionPay processing center. Each bank must develop a corresponding UnionPay Front-end System internally to connect with the UnionPay center for processing interbank transactions involving non-local bank cards.
