The Motley Fool's Dan Caplinger takes a look at the issue of credit piggybacking, and what the industry is looking to do about it. Basically, someone with a low credit score can pay someone with a better score to add them to their accounts as an authorized user, without actually using the account. There are companies that offer this "service" and, needless to say, the credit card companies aren't happy about it because it distorts credit. It allows completely irresponsible people to buy good FICO scores. It's no different than buying SAT scores from someone else to get into a good college.

While it's hard to have too much sympathy for the credit card companies, they have a right to be upset here. Fair Isaac (NYSE: FIC) has simply elected to stop considering authorized users when calculating credit scores, which seems like a logical step.

A crackdown on piggybacking could also lead to the demise of one of the easiest ways for parents to build credit histories for their children: adding them as authorized users. I'd like to see this end as well because the principle is the same. People should not get credit for stuff they had nothing to do with. It also reeks of nepotism, and seems unfair to kids whose parents don't have good credit. Do we really need to give rich kids another advantage? By piggybacking off their parents credit, kids with responsible parents can have great credit scores without ever having a credit card. Kids with less fortunate parents don't have that opportunity, and that's wrong.

There's no intelligent reason that piggybacking on credit should be allowed, and it will probably be stopped soon.
