Square PCI compliance: what Square handles, and your part

Square PCI compliance is simpler than many setups, because Square's hardware and software handle card data on its systems. However, your own habits and accounts still matter, so it is not entirely hands-off.

  • Not a QSA, stated first
  • Introductions to independent QSAs
  • Written answers, no call
Square pci compliance: use square devices, avoid side channels and protect accounts

What Square handles in Square PCI compliance

When cards are taken on Square's devices or its online checkout, card data is processed by Square rather than your systems. Therefore much of the technical burden sits with Square. Check Square's own documentation for its current position.

What you still own in Square PCI compliance

Your practices still matter. So review these habits.

  • Never writing card numbers down for later entry
  • Not taking card details by email or text
  • Protecting your Square account with strong sign-in
  • Controlling which staff can issue refunds

Common Square PCI compliance mistakes

Shared logins and paper notes with card numbers are the usual problems. Also, giving every staff member refund rights creates fraud risk. Each one is easy to fix once spotted.

Review staff permissions twice a year. It takes minutes, but it closes one of the most common gaps in small shops.

Where we help

We check side channels and account security, and confirm what your acquirer expects. However, we are not a QSA, and we are not affiliated with Square. The standard is in the PCI SSC document library.

Also keep a short note of how you confirmed Square's compliance each year. Your acquirer or a business customer may ask, and a dated record answers quickly. It also reminds you to review your own setup at the same time.
