Hi, I’m Vincent Bevia.
I work on payments at Multisafepay (part of Ant Group / Alibaba), and I’ve spent years designing and architecting Point-of-Sale (POS) systems — from traditional terminals to Android SmartPOS and SoftPOS (Tap-to-Phone). EMV, contactless, DUKPT, HSMs, key management — the whole stack.
Corebaseit is my blog. Here I write about:
- POS architecture and EMV — how it really works, not just the spec
- Cryptography in payments — lessons from real implementations
- What I’m learning about AI in payments — where it helps, where it doesn’t
- Engineering foundations — telecommunications, information theory, and stochastic processes
- Patterns, diagrams, and discussions from the trenches
I wrote Point-of-Sale Systems Architecture — Volume 1 and The Obsolescence Paradox: Why the Best Engineers Will Thrive in the AI Era, and do consulting for teams building payment systems. But this site is first and foremost a place for ideas, not a corporate brochure.
If you’re into POS, EMV, SoftPOS, or payment infrastructure and want to think and discuss — you’re in the right place.
