<prompt> Human: Im sure this has been discussed here before, but I cant find anything...pretty straightforward- I have one credit card, and its with my bank Chase. Its a cash back card. I would like to open another card with travel rewards. Chase Saphire has my interest, but my question is- should I open a card with another institution for diversification or does that not factor in to my credit score at alllenders dont look at that? I never carry a balance on my card and will continue to do so. Simply opening another account to take advantage of travel rewards and continue to build credit I also have a couple small loans.  <response>: It doesnt matter to your credit score, having a mix of account types is more important, i.e. credit cards, installment loans, etc.
