That's because this is a marathon, not a sprint, so it's going to take time to build up your kid's credit to the point where they will qualify for cards with better rewards that typically require excellent credit scores and lengthier credit histories.Because the average age of accounts is so important to your overall credit score, you'll want to help your child pick at least one or two options that are no-annual-fee cards that they can keep long-term. Having one or two older cards will help their credit score down the road.Reward your inbox with the TPG Daily newsletterJoin over 700,000 readers for breaking news, in-depth guides and exclusive deals from TPG’s expertsBy signing up, you will receive newsletters and promotional content and agree to our Terms of Use and acknowledge the data practices in our Privacy Policy.

Most of the changes introduced were positive for consumers, including giving individuals enough time to pay their bills and making it easier to pay off debt.Another change from the Credit CARD Act? Legal adults — think 18-year-olds — can no longer apply for a credit card without proof of independent income.This effectively eliminated the whole university campus "sign up for this card using your parents' income and get a free T-shirt" situation that used to exist.FREEMIXER/GETTY IMAGESHowever, if your 18-year-old is in college, they can apply for a student credit card instead. If your 18-year-old isn't attending a two- or four-year college, they can opt to open a secured credit card with a refundable security deposit instead.Related: Best credit cards for college studentsAdd your kids as authorized users — even before they turn 18Another solid option is to add your children as authorized users until they can qualify for other rewards cards on their own, which gives them your credit card with their name attached to it.You're responsible for paying off all their charges, so most parents only allow their children to use their cards for emergencies. But it's a great way to start teaching your children the importance of finances early on, plus you'll pool all their points into your account as the primary cardholder.COKADA/GETTY IMAGESSome issuers have age requirements for authorized users (American Express requires your child to be 13 years old), while others don't have any restrictions whatsoever (Chase, for example).This theoretically means you can add your child as an authorized user, even as an infant. You'll have to consider the right time for your child to be added as an authorized user, but this can happen well before they turn 18 years old with some issuers.Related: Best credit cards for authorized usersLength of credit is importantAnother important reason to start signing up your kids for credit cards when they turn 18 (or add them to your credit cards as authorized users) is that the average age of accounts is one of the biggest factors in determining your credit score.BLACKCAT/GETTY IMAGESSo acquiring — and keeping — a card when you're young can really give a boost to your credit score as you get older.Related: How to cancel a credit cardWatch out for targeted offersOne final note — watch out for targeted mailers. For most credit card issuers, the marketing departments don't always talk to the issuing and underwriting departments.Even with targeted mailers, it's unlikely that someone with limited credit history and income will be approved for a premium card, which typically requires good or excellent credit.FIORDALISO/GETTY IMAGESThis is why it makes the most sense to start small — consider the cards listed above — before your child starts applying for other credit cards.Related: How can I get a higher, targeted credit card introductory bonus?Bottom lineThere are several important considerations to factor into choosing your first credit card as an 18-year-old.Whether you're a parent with a healthy credit score and long-standing credit history or a teen on the brink of adulthood, start having conversations about how to best build good credit in order to qualify for premium cards, personal loans and more down the line.Related: College students: How to use your credit card responsibly
