Hello, I have an Amazing Box II and it is compatible with the Janome machine. The person would have to purchase the card (or use the one she has now) that goes with her machine. Actually the Amazing Box II will work with Babylock, Bernina Deco, Brother, SimplicityPES, Viking 1+, Rose 605, Artista ART, Janome JEF, Pfaff PCS, Singer XXX, Elna, Janome, Kenmore, New Home SEW.
There are 4 slots in this reader/writer machine. Each type of machine has a card that goes into it to read the design to sew out. The card that your sewing machine uses is the card that you will need to go into the Amazing Box II. Each of the slots are designated to specific formatted cards. Ex: Janome JEF, Brother PES, etc...
Hope that this helps.
