Can I safely transmit personal information such as credit card numbers?
You can enter your credit card number on a secure (https) form and transmit the form over the Internet to a secure Server without risk of an intermediary obtaining your credit card information. Secure communications does not eliminate all of an Internet user’s concerns. For example, you must be willing to trust the server administrator with your credit card number before you enter into a commercial transaction. Security technology secures the routes of Internet communication; security technology does not protect you from unreputable or careless people with whom you might choose to do business. The situation is analogous to telling someone your credit card number over the telephone. You may be secure in knowing that no one has overheard your conversation (privacy) and that the person on the line works for the company you wish to buy from (authentication), but you must also be willing to trust the person and the company.
