the card's size is 210x 198mm folded to 210X99

Yes I understand that part. Im asking about the resolution for it: is it to be done at 72dpi for digital use or 300dpi for print use? Dont wanna submit it too small for print usage or too big for digital usage. Trying to insure as high quaiity of a design as possible.

Oh, I am sorry,
For print please, 300 dpi

No problem. Thanks for the info. Ill start some designs now.
