Yep, you can reuse that same card until it wears out. I've had my embroidery machines for 5 years and haven't worn one out yet.

I cannot get my card to work in my Brother 270D. The program finds the designs I want and seems to write the designs to the card. But when I put it in my machine, it says the embroidery card cannot work on this machine. Any suggestions on what I am doing wrong. As you can tell, I am a novice
