I saw an ad for this on TV when I was at lunch. It is Visa's answer to allowing credit cards for Illegals.
However, I know some folks who are legal that this would be perfect for as well.

The Visa Reloadable Prepaid card is a smart and cost-effective alternative to carrying cash and paying check cashing fees. Because it is a pre-funded card, you only spend what money you load on it and you can typically get it without a credit check or bank account. Simply purchase the Visa Reloadable Prepaid card, load it with the cash amount you choose and enjoy the purchasing power of Visa. With the Visa Reloadable Prepaid card, you can make purchases and pay bills anywhere Visa debit cards are accepted - including retail stores, online merchants, and by phone. You can add money to your card at the retail location where you purchased the card or through direct deposit of your wages, tax refunds, or other government disbursements (See your card program rules for details).
