Hotel Network FAQ

If I am a hotel receiving payments from CSI Travel, what changes can I expect after I opt out of faxes?

Once you provide us with your email address for payments:

If your email provider supports Transport Layer Security (TLS) – you will receive a securely delivered email with full credit card information and the payment instructions

If your email provider does not support TLS – you will receive a FAX instead.

Payment emails will be delivered to you from an email address.

What is TLS?

Transport Layer Security (TLS) is one of the most widely used security protocols and ensures privacy between two email applications and their users so that a third-party cannot eavesdrop or tamper with the email messages exchanged between them.

When TLS is in place, people in both locations can send emails to each other without doing anything extra to encrypt the email.

How do I know if my email has TLS?

You can determine whether your email is TLS-enabled at

Enter your email address and click ‘Try It’.

We recommend working with your own IT support if you are unsure of the results.

Can I still receive payments if I don’t have TLS?

Yes! If TLS is not supported, you will continue to receive payments via secure, PCI compliant Faxes.

What is a Virtual Credit Card?

A virtual credit card is a unique credit card number that is generated to settle a specific transaction. There is no plastic card involved. Instead, the number is generated electronically and faxed or emailed directly to your hotel along with payment instructions.

The virtual card number should be processed like any other card not present for the transaction via your point of sale terminal. These virtual credit cards have several controls, including maximum amount allowed, validity dates, MCC (Merchant Category Codes) and how many transactions can be processed per card.

Virtual cards are most commonly used to cover room and tax with all incidentals to be settled by the guest on a plastic card.
