Generally printing house do not take small order for printing PVC cards ka. So, K.Fon suggested CafeThai buy their own card printer (roughly 40k Baht) and stacks of PVC cards (1,060 Baht /200 cards) and do the printing by themselves ka. Whenever there are new technicians, you can just print the Staff Card for them right away.
If you are ok with this idea, then P'Fon will source the best deal for you. And CafeThai will have to create PR form for the card printer and the PVC cards ka.
