The booking data never reaches the registration card
The guest entered name, address and companions when booking. At check-in they get a blank form. Booking system, PMS and registration are three worlds, although the data is the same.
Check whether the PMS can generate a pre-filled registration card, digitally signable before arrival or on a tablet. Most systems can; many houses never activated it. Use what is there first, then think about an extra tool.
