I am looking for some consulting advice to help me solve the following issue. My website securely stores credit card data for customers. I want to allow my customers the option (with their permission, of course) to use those credit card details to buy hotel rooms at hotels that they have selected.
For example, one of my customers will carry out a transaction with me that means that they want to stay at their favourite hotel. My site then needs to go to the hotel's site, and make the booking, right through to securely entering the credit card data. Obviously this throws up some major security issues.
I am looking for someone to give me consulting advice only as to how I can do this in a way that will be secure and acceptable to my customers.
