(CNN) — According to a recent survey by CreditCards.com, 8 percent of U.S. parents with kids under 18 have at least one kid who has a credit card.
The poll also found that 21 percent of parents said their children used their credit cards without their permission at least once.
According to the report, the more a parent makes, the more likely a child is to have plastic. Thirteen percent of parents who make more than $80,000 a year have a credit card-carrying child. That's compared with 5 percent of parents in the under $40,000 a year category with a child who has a card.
The survey found location may also play a role. Thirteen percent of children with credit cards live in the Northeast. Eight percent live in the South, and 5 percent in the Midwest.
Underage children can't apply for their own credit cards, but they can be added to their parents' card accounts as authorized users.
The downside to all of this, experts say, is kids can make unauthorized purchases and ruin their parent's credit.
However, there are benefits to giving your child a credit card. According to experts, having a credit card gives kids a head-start on building their credit and learning how to manage their finances.
