I’m Vincent Bevia. I work in payments at MultiSafepay (part of Ant Group), and I’ve spent years focused on POS architecture, EMV, and cryptography. I’m also the author of Point-of-Sale Systems Architecture — Volume 1 and The Obsolescence Paradox: Why the Best Engineers Will Thrive in the AI Era.

This blog is my space to share what I’m thinking about, learning, and discussing: POS systems, EMV, payment security, and, increasingly, how AI is reshaping this field. I also draw on my background in electrical engineering and telecommunications — information theory, stochastic processes, and thermodynamics — the technical foundations that sit beneath much of this work. Less corporate, more personal. Opinions, reflections, and the kind of things I’d talk about over coffee.

Topics I care about

• POS & EMV — how terminals, chips, and contactless payments actually work
• Cryptography & security — DUKPT, HSMs, and key management in the real world
• AI in payments — where it helps, where it doesn’t, and what’s coming next
• Engineering foundations — telecommunications, information theory, and stochastic processes

If you’re building payment technology — or just curious about how it all fits together — welcome.
