We’ve got this intuition that online communication is extremely secure thanks to encryption and other mechanisms. Or at least more secure than phone calls, which can be eavesdropped, or even tapped.

Here’s another crazy thing: phone calls are perceived to be safer for payments not because bank executives are old-fashioned. It’s because it makes perfect sense.

I’m Alvaro Duran, and this is The Payments Engineer Playbook. Go spend 5 minutes on Youtube and you’ll see tons of tutorials on how to pass software design interviews that use payment systems.

The reason I know this is because I’ve built and maintained payment systems for almost ten years. I’ve been able to see all types of interesting conversations about what works and what doesn't behind closed doors.

In The Payments Engineer Playbook, we investigate the technology that transfers money. All to help you become a smarter, more skillful and more successful payments engineer. And we do that by cutting off one sliver of it and extract tactics from it.
