The short answer

Compare terminal brands on things you can verify for the exact unit you are offered: whether that model, hardware version and firmware are on the PCI Security Standards Council's Approved PTS Devices list and when the approval expires; whether it meets the card networks' device and receipt rules; whether it is tied to one processor; what the contract or lease says; and whether it works with your POS software and peripherals. We do not rank brands, because model line-ups and prices change, so check each maker's own pages and your written quote on the day you decide.

Why this guide does not rank brands

Terminal makers refresh models, firmware and prices regularly, and the same model can be sold with different software depending on the processor that supplies it. A ranking goes out of date quickly and cannot tell you whether the unit in your quote is the version that was approved or supported. The checks below apply to any brand, and every answer should come from the manufacturer, the PCI SSC listing or your written agreement.

Check the PCI PTS approval

The PCI Security Standards Council keeps a public list of Approved PTS Devices. Its listing terms say only the specific version or versions of a product identified on the list have been evaluated, that compliance is determined by the PCI-qualified assessor or laboratory, and that PCI SSC does not test the products itself. Using a listed device does not by itself guarantee compliance. So match the model name, hardware version and firmware on your quote to the listing, rather than the brand name alone.

Check when the approval expires

PTS approvals carry expiry dates. In a bulletin dated 11 September 2025, PCI SSC extended the expiry date for PTS POI version 5 devices from 30 April 2026 to 30 April 2027. The extension applies only to devices already approved under version 5, does not permit new version 5 approvals, and PCI SSC strongly encourages migration to devices approved to PTS POI version 6 or later where deployment is not constrained. Ask the seller which PTS POI version the unit is approved under and the expiry date, and ask your processor how it treats devices after that date.

Check the card network device rules

Visa's Core Rules (18 April 2026) include an acceptance device table. It requires, among other things, that devices accept all 16-digit payment credentials, make available all payment interfaces the merchant supports, and, for contact chip devices, be approved by EMVCo in the regions the table lists. Receipt rules matter too: Visa prohibits printing the full card acceptor, merchant or terminal ID on the cardholder's copy for devices and gateways deployed on or after 15 October 2022, and for all devices from 16 October 2027, with an exception for hosts using PCI-validated point-to-point encryption or cryptographic keys. An older unit may need a software update or replacement to meet that date.

Check processor lock-in

In the US region, Visa's rules say an acquirer must not prohibit a merchant from using terminal processing services offered by competitors for delivering Visa transactions to VisaNet. That rule is about the acquirer's agreement; it does not mean a particular device can be moved to another provider. Many terminals are loaded with a processor's software and keys. Ask in writing whether the device can be reprogrammed for a different processor, who does it, and what it costs.

Check the contract, not just the hardware

The same terminal can be sold outright, rented month to month, bundled with processing or placed on a separate lease. Compare the total you will pay over the term, whether the lease can be cancelled, who owns the unit at the end, and how fast a replacement arrives if it fails. Our guides to leases and free terminal offers cover the clauses to read.

Check compatibility with how you sell

List what the terminal must work with: your POS or practice software, printers, cash drawers and scanners, Wi-Fi, ethernet or mobile data at the spot where customers pay, and how tips are entered. Ask the software vendor for its current supported-device list rather than relying on a brand's marketing page.

A worked example

Illustrative example only, with made-up round numbers. Quote A offers a terminal for $400 bought outright. Quote B offers the same brand at $0 upfront on a 48-month lease at $50 a month, which is $2,400 over the term. Before comparing screens, check both units' PTS approval version and expiry, whether each can be used with another processor, and whether the lease can be cancelled.

Key takeaways

  • Match the exact model, hardware and firmware to the PCI PTS listing
  • Ask for the PTS POI version and approval expiry date
  • Check Visa's device and receipt masking rules, including the 16 October 2027 date
  • Get reprogramming, ownership and lease terms in writing before choosing a brand
