If the thought of your 18-year-old on the loose with plastic in hand terrifies you, you likely share the sentiment of many parents in the same situation.
Lawmakers seem to agree as well, which is probably why the Credit CARD Act of 2009 has made it much harder for young adults age 18 to 20 to obtain their own credit card.
Under this new act, anyone under the age of 21 has to meet a few extra requirements before being granted a line of credit. They either have to either prove their income is high enough to pay off the bill or have someone over the age of 21 with sufficient income and credit co-sign (i.e. Mom or Dad).
