It requires that the code on the back of a captchalogue card is entered. Once this is done, the card must be inserted into a slot so that it can be punched. A punched card can no longer function as a Captchalogue card but can be used in conjunction with the Totem Lathe to carve a Cruxite dowel. The Punch Designix has a captcha code itself of L229BXOG, and Dave and Jade were able to upgrade the Alchemiter with it negating the need for the Designix itself. The relationship between a captcha code and the pattern on a card punched with that code is explained here.
