How Channel Managers Should Handle Card Data

Channel managers sit in a uniquely exposed position. They receive card data from OTAs like Booking.com and Expedia, and pass it downstream to property management systems, payment gateways, and revenue management tools. This makes them a critical—and often overlooked—point of PCI liability.

Many channel managers don't realise they're processing card data at all. They think they're just "forwarding" it. But in PCI terms, forwarding is processing. And if you're processing card data, you're in scope.

The Channel Manager's Hidden PCI Problem

Here's how most channel managers currently work:

1. An OTA sends a booking with guest payment card data.
2. The channel manager receives the card.
3. The channel manager forwards it downstream—to the PMS, to a payment processor, to a revenue management system, or all three.
4. The channel manager keeps a copy for records, logging, troubleshooting, or reconciliation.

In this flow, the channel manager is a pass-through for sensitive data. But pass-throughs still require security. The channel manager's servers, databases, logs, and backups all now contain card data. The channel manager is responsible for protecting it. The channel manager is in PCI scope.

And unlike a dedicated payment processor, most channel managers weren't built with PCI compliance as a core feature. Security was added later, if at all. Encryption might be partial. Logging might capture sensitive data. Backups might retain card numbers. Access controls might be loose.

Yet every payment the channel manager touches flows through their infrastructure.

Why This Matters: The Scale of the Problem

A mid-sized channel manager might handle bookings from dozens of OTAs and route them to hundreds of hotels. That's thousands of transactions per day, each one carrying a guest's card data through the channel manager's systems.

If even one of those transactions is mishandled—logged unencrypted, cached without expiration, backed up with card data intact, or exposed in a breach—the channel manager is liable. The OTA that sent it might face regulatory pressure. The hotels that trusted the integration might face questions. But the channel manager is the one holding the data in motion.

And here's the risk that keeps many channel manager founders awake at night: they're not sophisticated payment processors. They're software companies that handle bookings, inventory, and distribution. Security was never their primary mission. Now they're carrying PCI liability they didn't fully appreciate.

The Problem With "Secure Pass-Through"

Some channel managers respond by adding encryption, audits, and compliance certifications. They get PCI DSS certified. They harden their infrastructure. They hope this solves the problem.

It helps. But it doesn't solve the root issue: why does the card data need to be in the channel manager's system at all?

Encryption is good. Audits are good. Certifications are good. But they don't eliminate the risk. They just make risk management more expensive. Every data breach, every security incident, every audit finding now affects a channel manager's business—even if the breach was tiny and contained.

The real solution is simpler: remove the data.

The Right Approach: Tokenisation at the Channel Manager Level

Here's what needs to happen:

When an OTA sends card data to the channel manager, the channel manager doesn't hold it. Instead, the card gets sent immediately to a tokenisation service. That service returns a token—a safe, useless-without-context reference string.

The channel manager then forwards the token downstream. The PMS receives a token, not a card. The payment processor receives a token. The revenue management system receives a token. Everywhere the booking flows, only the token travels.

The actual card data never exists in the channel manager's systems. It never gets logged. It never gets backed up. It never sits in a database. It never gets exposed in a breach.

The channel manager's responsibility shifts from "protect all the card data flowing through us" to "make sure we're using a tokenisation service correctly." That's a vastly smaller scope.

How This Works in Practice

Let's say Booking.com sends a reservation with a guest's card to a channel manager. The current flow:

1. Channel manager receives card data.
2. Channel manager stores it temporarily.
3. Channel manager forwards to PMS.
4. Channel manager forwards to payment processor.
5. Card data is now in three systems: the channel manager, the PMS, and the payment processor.

With tokenisation at the channel manager level:

1. Channel manager receives card data.
2. Channel manager immediately sends it to Vaultera Vault (not storing it).
3. Vaultera Vault returns a token.
4. Channel manager forwards the token (not the card) to PMS.
5. Channel manager forwards the token (not the card) to payment processor.
6. Card data is now in one system: Vaultera. The channel manager, PMS, and payment processor only see the token.

The integration is straightforward. Vaultera provides APIs and webhooks. The channel manager builds one integration point (to Vaultera) instead of managing card data across multiple systems.

The Business Case for Channel Managers

From a business perspective, tokenisation at the channel manager level offers clear benefits:

Reduced Liability: No card data in your systems means dramatically reduced PCI scope. Audit obligations shrink. Liability exposure shrinks significantly. You're no longer the custodian of the most sensitive data in the transaction — and that changes your risk profile fundamentally.

Faster Integration: Instead of asking hotels and OTAs to trust your security, you can say "we tokenise all card data immediately." That builds trust with both sides of the marketplace.

Competitive Advantage: PMS companies and hotels want to work with channel managers that remove card data. Being able to say "our channel manager sends tokens, not cards" is a strong selling point.

Simpler Compliance: You're no longer the custodian of card data. Your compliance obligation is managing your tokenisation integration correctly, not securing sensitive data.

Better Incident Response: If there's ever a security issue, you can confidently say "Our systems never stored or processed the actual card data — only tokens." That's a powerful statement to regulators, acquiring banks, and customers.

Real-World Example: How Channex Does It

Channex, a leading channel manager in the travel tech space, handles bookings from multiple OTAs and routes them to hundreds of properties. They process thousands of transactions daily.

Rather than building their own card data infrastructure, Channex integrated tokenisation from the start. When an OTA sends card data to Channex, it gets tokenised immediately. Downstream systems—the PMS, the payment processor—only see tokens. Channex's systems only see tokens.

This approach lets Channex focus on what they do best: distributing bookings and managing inventory. It removes a category of risk they didn't want to carry. And it gives their hotel partners confidence that card data is handled by a specialist, not a booking system.

Reality Check

Reality Check: Tokenising at the channel manager boundary works best when the full data flow is aligned. If upstream OTAs or downstream PMS systems still expect raw card data in certain workflows, those flows will need to be updated. Vaultera's team works with you to map these flows before integration, so the architecture is clean from day one.

Start Here

If you're a channel manager, audit your current card data flow:

• Where does card data enter your system?
• Where is it stored?
• How many times is it copied or forwarded?
• What logs contain card data?
• What backups contain card data?
• How many downstream systems touch it?

Each of these is a point of liability. Each one can be eliminated by tokenising at the point of entry.

Vaultera Vault is built for this exact use case. Channel managers integrate once, and card data gets tokenised the moment it arrives. The token flows downstream. The actual card data never enters your infrastructure.

The question isn't whether you can manage card data securely. The question is whether you should—or whether you'd rather remove the data entirely and let a specialist handle it.

Your hotels will be safer. Your OTA partners will have more confidence. Your compliance burden will shrink. And your engineering team can focus on building features, not managing payment card security.

That's the channel manager advantage in modern travel tech.
