To increase fraud protection, most card brands use a security validation code with a payment card, such as a CVV (card validation value), which is typically a three-digit number on the back of the card. Although CVV is used by Visa, the term is generally used by all card brands. You can maximize profits and limit revenue loss from credit card payments by passing the security code to complete an online order. You must enable the POS to accept the security code value in Maintenance > Payments > Tenders > Security Verifications tab.

To enable the passing of the payment card security code:

• Select Configuration > Company Settings Setup.
• Type CVV in the ‘Setting’ text box until you find the ‘CVVEnabled’ value.
• Click Edit Setting.

• Type True in the ‘Value’ text box.
• Click Update.
  When enabled, the Security Code option appears for a desktop user.

The Security Code also appears for a mobile web user.
