How is credit card made?


I know lot of credit cards run on linux as an app despite gov claiming "it has its own linux system." Elon Musk built X.com, or Paypal. What software and program did they use to make modern day PayPal, and Visa Cards?

Interior please. #linux

thank you.

Are you asking how payment providers work, or are you asking how ecommerce platforms work?

Typically, the data flow is: "ecommerce platform" --- "payment information" --> "payment provider" --> "ecommerce platform"

You can't "build your own Visa...system"
You want to create your own payment accepting/processing system?
In other words, you want to re-invent the wheel?
Why?

Do you want to launch your own credit card, or are you actually talking about Visa cards?

Never followed up in either of those, and both questions weren't clear or seemingly thought out too well. As is this one...you seem to be wanting us to explain to you how to start your own credit-card company, which has nothing to do with Linux. And now you're intentionally trying to troll with responses like this. No, thanks...feel free to go look up how banking and finance works on your own.

The OS has little to do with the program you are considering. That would need to have a secure means to "transact" actions. It would require secure "trusts" in the form of peer to peer. You of course would have to receive some gain, usually in each transaction. The type of currency would have to be agreed upon or in exchanges.

I used to work on big name company systems that were used for banking and such. There were various safeguards both in hardware and software. Each transaction in minute detail was monitored by multiple tasks.

It would be difficult to make an system that didn't violate copy protected methods. Not impossible but these guys have been at it for decades.

I'd move this post but not sure where best to place it.

First start with a large financial backer/banker/angel/investor etc... Then sign a license with Visa....but beginning to think you might be a kid that's just mad someone said no about using their card.

Actually there is a question in here struggling to get out. I understand that the processor built into modern bank cards receives from the PIN machine the PIN you typed in, encrypts it and compares it with its stored encrypted PIN. Then it sends a TRUE/FALSE signal to the machine. Likewise if you change your PIN, the processor can receive the new PIN, encrypt it and store it.

So how does it do that? Is it running a single program or is there some kind of mini-OS on it?
