As of now the customize interface does not have an option for the credit card pocket area.
Whatever image you lay over the inside of the wallet that also covers the credit card area will be printed on both areas. For example if you put a sunset image on the inside of your wallet the entire image will be printed in full across the inside of the wallet and over the credit card pocket seamlessly.
Full Customization with Credit Card Art being separate are possible by downloading the PSD and Illustrator files
If you want to add separate artwork to the credit card pocket area you can do so with these templates. Save 3 separate files for the output: Front, Back and Credit Card with only the art you want showing for each panel.
You can download Photoshop & Illustrator templates here
Place your order with a place holder for the images you want to use and make a note on the customization interface that you are using the PhotoShop or Illustrator templates and email your files to tk@dynomighty.com
