Can I trust virtual assistant with credit card info?

[Jonathan Farber]

Hey all, like many people here, I am looking to delegate/automate some tasks through the help of virtual assistants.  Through sites like Freelancer and UPwork, I have found great help for about 20 projects.  Things like research, organizing data, Etc.  At this point, I am looking for help on projects that may require some of my financial information.  Is there a way to securely do this that people with experience can recommend? 

I have heard some recommendations for separate accounts, credit cards, or debit cards just for this use.  Thanks all for any feedback!
