You can send your works as vectorial in .eps, .cdr, .ai, .pdf or .psd formats. Besides you can share them in also .jpg format but we suggest them to be at 500 DPI resolution for high quality print. Standart card sizes for plastic cards are (CR-80) 85,6*54 mm same with credit card sizes. But the design area must be 89*58 mm so as to have at least 2 mm depth for cut.
