Accounting Applied to Payment Methods - P1

One of the most underrated—and often underutilized—components of the jPOS technology stack is MiniGL: a real-time, highly scalable, double-entry accounting system. Both jCard, our issuing platform, and jPTS, our acquiring platform, make extensive use of MiniGL and several of its distinctive features designed specifically for the card payments industry. Concepts such as layers, tags, and partial balances work together to form a robust, best-in-class accounting framework.

We are now sharing with the community a selection of the materials we use to train our own developers. These resources are intended to help engineers better understand the complexity and inner workings of issuing and acquiring systems that process payment messages at scale.

This post introduces installment 1 of 3 in our internal development tools series. We hope you find it useful—feedback and questions are very welcome.
