If you register with a legitimate online casino that has a valid license number and strong online security measures, then yes, it is safe to provide your personal and banking information to a casino. Casinos use this information to verify your identity and age as well as secure your account, information, and winnings.
There are many ways to check an online casino’s use conditions for personal identification information. Most online casinos explain how they use your personal information to verify your identity and age as well as secure your account and winnings before or during the registration process. For example, one online casino may dedicate the page before entering the registration form to explaining their use of your personal identification information, while another online casino may have a blurb on the registration form itself.
You can also check an online casino’s use conditions for financial information, including your credit card, debit card, digital payment platform, or bank account information. Many online casinos explain this on the page before entering the registration form or on the form itself.
In addition, many online casinos also have FAQ pages, which you can (and should) view before clicking the button for registration or creating an account, where they explain their use and storage of your personal identification and financial information.
To further demonstrate their security, most online casinos also have a section of their website dedicated to explaining the security measures, software, and other relevant information. You may find this on its own page and/or in the FAQs.
