How do I ensure my fare filing workflow with booking engine software is PCI compliant?

To make a fare-filing workflow with booking engine software PCI compliant, focus on how payment data enters, moves through, and is stored by the system. The big goal is to keep card data out of your fare-filing workflow entirely whenever possible.

Practical PCI compliance checklist

1) Minimize card data in the booking/fare-filing process

• Do not let card numbers, CVV, or magnetic stripe data pass through fare-filing tools.
• Use a PCI-compliant payment gateway or hosted payment page so cardholder data is captured outside your booking engine.
• Prefer tokenization so your system stores a token, not the actual card number.

2) Segment systems and reduce PCI scope

• Keep the fare-filing environment separate from payment processing systems.
• Ensure booking engine software does not touch raw card data unless absolutely necessary.
• Use network segmentation, restricted access, and separate credentials for systems that handle payments.

3) Use PCI-compliant vendors and contracts

• Confirm your booking engine, GDS, payment gateway, and hosting provider each support PCI requirements.
• Get written assurances such as:
  • PCI responsibility matrix
  • AOC (Attestation of Compliance) where applicable
  • Shared responsibility documentation

4) Secure data in transit and at rest

• Use TLS 1.2+ for all transmissions.
• Encrypt stored sensitive data, but note: CVV must never be stored after authorization.
• Mask PANs in logs, reports, emails, and admin screens.

5) Don’t log sensitive authentication data

Make sure your workflow does not store:

• CVV/CVC
• PIN/PIN blocks
• full magnetic stripe data
• sensitive authentication data after authorization

Also review:

• application logs
• API request/response logs
• debug logs
• error messages
• analytics tools

6) Control access tightly

• Use least-privilege access for agents, admins, developers, and support staff.
• Require MFA for administrative access and remote access.
• Review access regularly and remove unused accounts.

7) Secure the booking engine software

• Keep software patched and supported.
• Perform vulnerability scanning and, if applicable, penetration testing.
• Use secure coding practices if the workflow is custom-built.
• Restrict administrative interfaces.

8) Build compliance into business processes

• Train staff not to collect card data in chat, email, or free-text notes.
• Use structured payment fields or hosted checkout instead of manual entry.
• Establish procedures for incident response, change control, and periodic review.

9) Validate the correct PCI level

Your required validation depends on your transaction volume and architecture:

• Many smaller businesses complete a Self-Assessment Questionnaire (SAQ).
• More complex environments may require a QSA assessment and more formal audits.

Recommended architecture

The safest design is:

Customer/Agent → Hosted PCI payment page or tokenized gateway → Booking engine receives only token/authorization result → Fare filing proceeds without card data

That usually keeps your fare-filing workflow out of the highest PCI scope.

Common pitfalls

• Storing card data in PNR notes, CRM fields, or fare-filing metadata
• Allowing agents to paste card numbers into free-text fields
• Sending card details via email, chat, or support tickets
• Logging full payloads from payment APIs
• Assuming “encrypted” means “out of scope” without proper PCI design

Best next steps

1. Map your current data flow.
2. Identify exactly where PAN/CVV enters the system.
3. Replace any direct capture with hosted checkout or tokenization.
4. Ask your vendors for PCI documentation.
5. Complete the appropriate SAQ or engage a QSA if needed.
