Hi, I’m Vincent Bevia.
I work on payments at MultiSafepay (part of Ant Group / Alibaba). Day to day that means design system engineering for POS, payments, and security — traditional terminals, Android SmartPOS, SoftPOS (Tap-to-Phone), EMV, DUKPT, HSMs, orchestration, and the ops that make settlement trustworthy.
Corebaseit is where I publish that thinking. Not a services pitch — a record of what I know and how I reason about these systems. Here I write about:
- Design system engineering — channels, platform, crypto infrastructure, and finance ops as one stack
- POS architecture and EMV — how it really works, not just the spec
- Cryptography in payments — lessons from real implementations
- AI in payments — where it helps, where it doesn’t
- Engineering foundations — telecommunications, information theory, and stochastic processes
I wrote Point-of-Sale Systems Architecture and The Obsolescence Paradox. This site is for ideas, diagrams, and discussion — so people can see the depth of the craft.
If you’re into POS, payment architecture, SoftPOS, or secure infrastructure and want to think and discuss — you’re in the right place.
