>Consumers under the age of 21 must prove that they have an independent income or get a co-signer before applying for a credit card. The Act also prevents credit card companies from ... wooing students with T-shirts, free pizza and other free gifts at university-sponsored events
[edit] The end of the story for me:
The credit card I got from that was amazingly bad. I had a bill put in the wrong mailbox in my dorm, so didn't get it until 3 days before it was due. I called up customer service:
Me: I can mail this today, but it is unlikely to make it there by the due date, I've always paid my bills on time, can I get a 1 week extension
CS: We can do an ACH for $20 or you will pay a late fee if the check you mail is even a day late.
Me: Seriously?
CS: Yes
Me: Okay, do that and cancel my account.
CS: Okay.
It's like they didn't even want me as a customer if I was going to pay my bills every week. Not a single attempt to retain me when I canceled my account. At this point, I had a Discover card, the CS reps for which were very kind, and my bank had just gotten my debit card on the Mastercard network (previously it was only an ATM card), so I had no absolute need for their card. Had this happened a few months earlier I might not have been willing to cancel as so many places don't take Discover.
I semi-suspect you know this, but if you pay in full every month, they don't get to bundle your debt up and sell it off as a security. Interchange fees are competitive enough that it's probably close to break even (and getting more so every year), but the securities are comparatively pretty sweet for the issuers.
* They earn money via the interest people way if they don't settle their bills in-full, and on-time.
* But they also take money for handling transactions at terminals, etc.
No "might" or "slightly" about it. It's significantly different now. When I was 18 you only needed a faint pulse to get 10s of thousands of dollars in credit. People would hand out credit applications in dorm rooms, at events, in front of classrooms, just anywhere and everywhere you could think of. It was a different time.
In less than a minute, BoA’s automated credit card application approved me and mailed out a $1000 limit card.
It seems strange that taking on a ton of unsecured debt would make creditors think it's more likely that you'll be able to pay off even more unsecured debt, but that seems to be how the system works, or at least worked two decades ago when I was in school. Perhaps the emergence of for-profit colleges that don't really offer their graduates the kind of post-schooling opportunities that traditional colleges do has changed the way that college loans are perceived since they no longer reliably predict future earnings the way they used to.
FWIW, when I was 18 I had to get a secured card[0] and I was barely able to get it (I had to go to my bank twice to appeal the decision). It's definitely different from 40 years ago but it's not super easy for most college students, and a lot of it came down to the fact that I had a few grand sitting in a checking account and a job that paid $12.50/hr. Some of my friends who didn't have that got flat out declined multiple times (I have one friend who has applied for three different cards and she's been denied all three times, with no credit history at all).
[0]: Basically, the card had a $500 credit limit and you had to give the bank $500 for a year, after a year if you've made all your payments they give you your $500 back. It still sat in my savings account generating "interest", but I couldn't spend it
