Can I have the same game card in 2 xbox360 at the same time without using a memory card?

I have 2 360 at home but cant figure out a way to have my gamer card on both 360.
The only option i found was the Card recovery but that deletes the saves on the original console.

thx 4 the help!

The only ugly way to do this is put your profile on a memory card and move it between 360's.
