Yeah don’t go that route. I’m saying this as someone who has decades of experience specifically in software security and database development. You need more software security and database knowledge than three people can learn in 20 years, and even then you’re fucked with hidden fees and some imaginary PCI compliance status that you’ll never achieve. They didn’t have these types of blockers when Amazon and eBay were made, but they don’t want any competition now do they? So now the credit card companies and fuckheads in charge of all these businesses created these policies for the banks and credit card companies so that people like us can never touch their level of success. Banks, credit card companies, and everyone in between will gloriously fuck you in the ass if you try to do it on your own. And you’ll give them thousands of dollars while they do it. So if that sounds fun, then go right ahead. Otherwise, stay far away.
