Are You Sure Your Credit Card Security Would Pass a PCI 4.0 Check?

Most businesses think they’re “probably fine” until a processor, insurer, or auditor proves them wrong.

You could ask AI what PCI 4.0 is.
 You’ll get a long
, generic answer and still be stuck with the real question:

“What does this actually mean for my business, my staff, and my ability to take payments tomorrow?”

That’s what this guide is for.

It cuts through the noise and shows you:

  • Where most businesses slip up with PCI 4.0 (and don’t realize it)
  • How staff habits (emails, spreadsheets, saved card info) quietly break the rules
  • What your processor expects you to prove if there’s ever an issue
  • The first few steps you can take this month to reduce your risk

No jargon. No 80-page compliance PDF. Just the parts that actually matter if you accept credit cards.

Why not just ask AI?

Because AI gives you information.


This guide gives you:

  • A survival checklist you can print and use in a meeting
  • A quick self-assessment to see if you’re already exposed
  • Real-world scenarios for retail, healthcare, professional services, and hospitality
  • A clear path to talk with your IT provider or MSP about fixing gaps

If you’re guessing, you’re gambling. This guide helps you stop guessing.

I have never had a better IT person then Alternis IT.  All my electronics run so perfectly now. He helped me completely set up my new office, as well as keeping it running so smoothly.  He is always available to assist  us when something comes up. Customer service, professionalism, skill, knowledge. He is amazing.  I would 100% recommend them for all IT needs whether you are a small business or a huge company.

Our company uses Alternis IT as the primary IT provider; they resolve our day-to-day end-user issues and also as an IT consultant and management firm for larger projects (for instance, we're in the middle of office expansion project now).

They provide us 24/7 technical support specialists to our end-user needing quick and effective responses. Staff are available and knowledgeable and work around the tight schedules of our internal team. On larger projects, I frequently turn to Alternis IT for advice on anything IT related and trust that their knowledge and intel make our life easier.

Overall, I find working with Alternis IT to be an excellent experience. From daily troubleshooting to more significant projects to organizational strategy, I trust their expertise and professionalism. I would highly recommend their services.

Alternis IT team helped set my office up the first time when I moved to my new office.  They are super-organized and neat.  Art was knowledgeable and made sure I knew what type of products would best fit my needs and developed custom IT systems that were secure, fast, and reliable for my business. He also installed the network cables for us.  I most certainly recommend Alternis IT.
