Card Act Requirements- Lines of credit

It's been a long time since I've looked in detail at the Card Act. The pertinent provisions of the regulation speak frequently to "Issuer" and "credit card account". But, do unsecured, open-end lines of credit, used for overdraft or other purposes, need to follow all of the same requirements? I'm particularly looking at online applications, and how/where to present the disclosures during the application process, and whether the ability to repay requirements, including those for young consumers, also apply to these non-credit card products. TIA!

If there is no card then Subpart G of Regulation Z does not apply.

Thanks, Randy. That's what I thought, but it threw me since Subpart G says "Credit Card Accounts and Open-End Credit Offered to College Students". It seems like it makes it broader than credit cards...
