If you encounter a message indicating that your email address is already taken, it is possible that you may have previously registered an account but did not complete the process or have forgotten about an existing account.

1. Verify Existing Accounts:
   Check if you have previously registered for an account using that email address. Try using the “Forgot Password” or “Reset Password” option to regain access to your account.
   
2. Use a Different Email Address:
   If you are unable to recover or access the existing account, consider using a different email address to complete the registration process.
   
3. Contact Customer Support:
   If you believe that there is an issue with your email address or if you need assistance with account recovery, contact LookCard customer support. Provide details about the issue and your email address for further assistance.
