Also called: Semi-Integrated Solution
What semi-integrated payments are
A semi-integrated payment setup separates your point-of-sale software from the application that handles card payments. Your POS can send the amount and transaction request to a payment terminal, while the terminal’s payment application handles the card data and connects to the processor or gateway.
The terminal sends the approval or decline back to your POS so it can complete the sale. In this arrangement, the card number does not pass through the POS or your connected back-office systems. Your POS still receives transaction details needed for checkout and records.
Semi-integration can shrink the systems in your PCI scope, but it does not make compliance automatic.
How the payment moves
A common setup uses a POS app on a computer or tablet and a separate terminal connected over a local network. Another option puts the POS app and payment acceptance on one smart terminal. In both cases, the payment application handles card data separately from the main POS software.
The terminal can encrypt card data and send it directly to the intended processing host or gateway. Some solutions also return a token, an identifier used in place of a card number for later transactions. The specific devices, software connections and token features depend on the solution you choose.
Why it matters for your business
Keeping card data out of your POS reduces the number of systems involved in protecting it and can reduce the scope of your PCI DSS assessment. That can mean fewer systems to assess and secure. It does not make your business automatically PCI compliant or remove every payment-security responsibility.
The exact scope depends on how the POS, terminal and other connected systems are configured. If an integration change routes card data through your POS, the security boundary changes. In the US, PCI DSS v4.0.1 is the current standard as of 2026, and processors commonly bill a monthly PCI non-compliance fee when a merchant has not validated compliance.
What it means for your costs
Semi-integration does not set your interchange, network assessments or processor markup, and there is no standard processing discount attached to the architecture. The research materials do not specify a standard setup fee or savings amount. Compare the quoted software, terminal and integration charges with your current setup before treating a security or implementation benefit as a cost saving.
A separate payment application can also make POS updates less likely to require payment-system recertification, depending on the change and solution. Confirm which updates your POS vendor handles and which changes require payment integration work. The architecture itself does not appear as a standard line item on a processing statement.
What you can actually change
- Trace the data path. Ask which systems receive the card number, and confirm it does not enter your POS or back-office network. Get the answer in writing for your PCI records.
- Confirm PCI scope. Ask which systems and tasks remain in your business’s PCI assessment after installation. Do not assume a semi-integrated label removes your validation or security duties.
- Compare total charges. Separate terminal, software, integration and processing charges in the proposal. Compare each with your current costs rather than relying on an unpriced claim of savings.
Frequently asked questions
Does semi-integrated payment processing make my business PCI compliant?
No. Keeping card data out of your POS can reduce the systems in your PCI scope, but your business still has compliance responsibilities. The remaining scope depends on your configuration and how card data moves through connected systems.
What is the difference between integrated and semi-integrated payments?
In a traditional integrated setup, card data can pass through the POS and connected systems. In a semi-integrated setup, the POS sends a transaction request to a separate payment application, which handles the card data and returns the result.
Do semi-integrated payments lower processing fees?
The architecture does not set interchange, network fees or processor markup, and it has no standard processing discount. Compare the actual software, terminal, integration and processing charges in your proposal to determine whether your total costs change.
Can I use a semi-integrated setup for pay-at-the-table?
Yes. A smart terminal can run the POS app and payment acceptance on one device, supporting mobile checkout such as ordering and paying at the table. The available functions depend on the devices and software in your solution.
