My oldest kid just turned 18 and I was wondering if there are any credit cards recommended for an 18 year old to start building their own credit history. I had added him to my Amex cards as an authorized user when he turned 15 but figured it was good to have him get his own card, if possible. He's a high school senior so he doesn't have much income. During normal times he does groups in shul and makes about $100 a month from that. But he doesn't really have any other income.
Or does it make more sense to just wait until he's 21?
