How do I ensure my mobile giving checkout with a donation platform is compliant with PCI requirements?

To make a mobile giving checkout compliant with PCI DSS, the key is to minimize how much card data your app or systems ever touch and use a PCI-compliant payment flow/provider.

Best-practice approach

Use a hosted or tokenized payment solution so that:

• Card numbers are entered in a PCI-compliant payment page, iframe, or SDK
• Your mobile app never stores or transmits raw card data
• Your systems only receive a token or payment confirmation

This usually reduces your PCI scope significantly.

What to do

1. Use a PCI-compliant payment processor / donation platform

Choose a provider that offers one of these:

• Hosted payment page
• Hosted fields / embedded secure fields
• Mobile SDK that keeps card data out of your app/backend
• Tokenization and vaulting

Ask the provider for:

• Their PCI DSS level
• Their AOC (Attestation of Compliance)
• Which SAQ type your integration qualifies for

2. Avoid handling raw card data in your app

Do not:

• Capture card data in your own UI and send it through your servers
• Log cardholder data
• Store PAN, CVV, or magnetic stripe data
• Use analytics/crash tools that might capture sensitive fields

3. Keep your app out of PCI scope where possible

Prefer:

• Redirect to hosted checkout, or
• Embedded secure fields controlled by the provider

If your app directly collects payment details, your PCI obligations increase a lot.

4. Secure the mobile app and backend

Implement:

• TLS everywhere
• Certificate validation; consider certificate pinning where appropriate
• Secure secrets handling
• Strong authentication for admin access
• Least-privilege access
• Regular patching and dependency updates
• Secure session management
• Runtime protections for mobile app where appropriate

5. Protect all supporting systems

PCI can apply to systems that can affect payment security, including:

• Backend APIs
• Web servers
• Admin dashboards
• Logs
• Customer support tooling
• CI/CD pipelines if they can alter payment code

6. Do a PCI assessment of your exact architecture

Compliance depends on how the checkout is implemented. You should:

• Map the flow of card data end-to-end
• Identify where card data could touch your systems
• Determine the applicable PCI DSS scope
• Complete the proper SAQ or a formal assessment if needed

Common mobile donation patterns

Lowest PCI burden

• App opens a hosted donation page in browser/webview
• Payment provider handles card entry
• App receives only a success/failure result

Moderate burden

• App uses provider-hosted fields / SDK
• Your app submits non-sensitive donation details
• Provider returns a token/payment intent result

Highest burden

• App captures and sends card details to your backend
• This creates significant PCI scope and should generally be avoided

Important note

PCI compliance is not just “using HTTPS.” Even with TLS, if your app/system handles card data directly, you may still be in scope.

Practical next steps

1. Ask your donation platform whether they offer hosted checkout or mobile SDK/tokenization
2. Get their PCI documentation/AOC
3. Diagram your payment flow
4. Confirm which SAQ applies
5. Have a qualified security/compliance professional review it if you’re unsure

If you want, I can help you evaluate a specific donation checkout architecture and tell you what PCI scope it likely falls into.
