To verify and check the accuracy of the credit card number, select INVOICE TOOLS and VERIFY & CHECK ACCURACY OF CARD NUMBER from the pull down menu.  You can also verify a number by clicking on the "V" button found on the Main Invoice Screen adjacent to the Credit Card Number and Expiration Date.  Or you may paste a credit number and verify it automatically by right clicking in the Credit Card Number blank.

All credit card numbers issued by major credit card companies must meet a mathematical test for correctness.  AnyOrder has a built in process which runs the mathematical test and checks the number.  Once the test is completed, a message will appear telling you whether the number is valid or not.

Even if you don't use AnyOrder's built in card processors, you'll find this a handy feature.  By using it, you'll know right away if you've accidentally typed in the number incorrectly--or someone has given you an improper or fraudulent number.  You'll still need to process the card through the processing center, but this quick check can save you considerable time should the number not be accurate.
