As a business owner/manager, use Kardder to promote your business with our proprietary Pin and Park feature to make sure potential customers always have your contact information within reach. Also, use Kardder to provide custom branded cards for your employees. Put them to work as brand ambassadors, promoting consistent branding to potential clients and vendors, especially important for sales associates, and other promotional positions.
