I have a Bernina 730...and you can use a card with preloaded designs..you can load them directly from the computer using a usb port..or you can download them to a usb stick and plug it into the side of the sewing machine. I have a Husqavarna (spelling) Iris and it only has a card and you have to use a card reader to download designs..which I found way to confusing. I hope this helps.
