I have a cash-rewards credit card at my bank; I have a second cash-rewards credit card I use only for internet purchases (I feel safer not exposing my "main" credit-card to the internet). I recently got an offer from Fidelity for a 2% credit card which looks attractive. But I already have lots of auto-pay accounts linked to my bank credit card and I've never used a credit-card not associated with my regular bank, so I wanted to try out the Fidelity one first without making it my main credit card, just as a test. That means I would have three credit cards. Is this a problem, credit-rating, or other- wise? How many credit cards can you have before it becomes a problem?
Any help will be apprecited.
I didn't find the right solution from the Internet.
