The following is a demonstration of the new ON-LINE CHECK SYSTEMS by AUDIO CHECK.  This systems allows consumers to purchase products and services over the web using a standard check procedure. The customer supplies the vendor with the Check No., Bank Name, Routing Number, and the Dollar Amount of the Check. The customer retains his or her physical check for their record keeping. The vendor processes the order and then delivers the products or services when the check is processed.  ON-LINE CHECK SYSTEMS will also work for vendors who want to take orders over the phone or fax.
