I am hoping to get my grandparents a credit card to help them more easily pay their mail-order prescription drug plans. They have never had a credit card, and I ran their Equifax report and there are only two tradelines, both fully-paid bank loans in good standing within the past year. They are in their early 80s and have social security income and some investment income. Can anyone recommend a good card for them? They will pay their balance in full each month, and want no annual charge. Also, the sooner we can get this the better, so quick turnaround for applications is important. Thank you!
