You may have been advised historically that when booking foreign hotels and paying by card to pay by card and send the details by fax. As fax machines are now rare and present a security risk, do not use fax machines to send credit card details wherever possible as fax printouts can be easily intercepted.
If you must book hotels without using Click Travel as the provider, and are paying by card, please inform the hotel directly either by telephone, or in two separate emails, from the kent.ac.uk staff address and ensure the confirmation comes to your staff account. Any confirmation should not contain the full card details but only the last four numbers. This will reduce the risk of card cloning and fraud when booking.
