In fact, it’s probably something of a misnomer to call it a prepaid credit card, since no credit is involved and, therefore, there’s never any interest to pay. Whenever you use it (in exactly the same way you would use any of your other plastic), you’ll only be spending money that you’ve already loaded onto your prepaid card. So, there’s never any danger of getting into any debt on a prepaid card.
Another great benefit of having a prepaid debit card is that you can send money to your loved ones without hassle. Parents will not find prepaid debit cards as useful tools in sending allowance for their kids in college.
