Welcome to Corebaseit — my blog on POS, EMV, payments, and AI.

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

This is where I share what I’m thinking about, learning, or discussing — less corporate, more personal. Opinions, reflections, diagrams, and the kind of stuff I’d talk about over coffee.

You’ll find:

• POS and EMV explained clearly
• Cryptography in payments — DUKPT, HSMs, key management
• SoftPOS, Tap-to-Phone, and MPoC
• Thoughts on AI in payments — where it helps, where it doesn’t

If you’re building payment tech or just curious how it all fits together — welcome. Let’s discuss.
