Activating a credit card online is not a safety risk as long as certain precautions are followed, such as checking the security of the website and using a secure Internet connection. Users should avoid activating online if the website address does not begin with "https:", which indicates a secure website.
A customer should always ensure that he is the one beginning the activation process. For instance, he should avoid activating a card from a link received in an unprompted email or text message. Cards should not be activated using an unsecured public Internet connection.
If the customer cannot activate a card online through a secure connection, the card can also be activated via phone.
