A Flexible RESTful Payment Switch Based on ISO 8583

Horizon Payment Switch

Horizon Payment Switch is a research and development project to create a free and open source payment switch based on "Distributed Open Banking Theory". It will be developed by Python programming language. Horizon is a payment approach based on ISO 8583 standard which is following the distributed data management architecture. It will be a script based payment switch to implement changes with minimum cost. Horizon will be connected to any gateway and terminal by REST services. It will try to achieve an appropriate transaction per second (TPS) rate.

Project Status

The project status is "underdevelopment".

7 - Easy to Use

Research Goals and Questions

1 - Is it possible to develop a RESTful payment switch based on ISO 8583 which can convert ISO message to REST format and vice versa with minimum process?

2 - Is it possible to create a payment switch based on ISO 8583 standard which clients can inquery format of specific message (ex: input and output for 0200 request message type) for the switch?

3 - Is it possible to create a flexible RESTful payment switch which aministrators can map ISO fields to JSON parameters without restarting or switching off payment gateway or switch?

4 - Is it posible to develop a payment switch which uses RESTful (HTTP) and socket programming (TCP) connection methods at a same time to provide payment services for deferent types of clients (ex: ATM and mobile app server)?
