Difference between secured credit card and student discover card?

Hi

i am looking to start building credit now that i am 19. I keep getting offers of a discover credit card. I was wondering if its better for me to get the discover student card or if i should get a secured credit card from the bank. I currently dont have credit but i think discover opens up cards for students without credit.

thanks
