Verifying Last 4 Digits on Credit Card by USANA

USANA verifies the last 4 digits on a credit card number before processing an order primarily as a means to protect our customers from fraudulent charges.

We also need to verify which form of payment they want to use if there is more than one form of payment on the account.
