Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getCardCVV([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setCardCVV([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

Remarks

Three digit security code on back of card (optional).

This alphanumeric field contains the three digit Visa "Card Verification Value" (CVV), MasterCard "Card Verification Code" (CVC), or four-digit American Express "Card Identification Number" (CID). This value appears as additional characters embossed on the card signature line following the credit card account number on the back of the credit card. This is an optional field which can be used to determine if the customer is actually in possession of the credit card.

Even if the CVV data is incorrect, the transaction may still be authorized. It is up to the merchant to examine the field and decide whether to honor the transaction or not.

Character length and limitations: Up to four single-byte numeric characters.

This property is optional.

This property is not available at design time.
