I need a Credit Card, which one to get?

Yea im in the same boat. I suppose i dont really care about interest as much since i dont plan to buy anything i wont pay off immediatley. I just think i should build some credit as i plan to buy a house in a year. Do i really need to do this when applying for a home loan, cant i just show them i have money in the bank i dont really want a credit card.
