Medco's online ordering service, Express Scripts, uses up-to-date security measures to protect the financial and medical information of its clients. Credit card information is stored separately from medical information and kept on a server that is not connected to the Internet for extra security.
While Medco allows customers to store personal information on its website for convenience, it doesn't require them to do so. Customers can call in to disclose any needed information instead. Customers are not required to provide their Social Security numbers, and Medco promises not to disclose personal or medical information to any other company. It also asks for identifying information known only to the customer to activate services and confirm identity.
