Getting paid to do online surveys can be a Catch-22. On one hand it is great to get paid money to voice your opinion. On the other hand, to get paid you might have to give out personal information -- like a credit card number or your social security number.
In this case you may want to use a virtual wallet. This is an e-account you set up so survey companies can automatically deposit the money, then you can transfer it to your bank account. The benefit here is an extra layer of security. You don't have to release any bank account or credit card info to the survey companies themselves. Paypal is one of the more popular companies.
However, before you sign on look over all of the conditions an online pay company sets. They might seem similar to a regular bank, but not in all areas so make sure you understand the differences.
