What is Card Verification Method (CVM)?
The Card Verification Method, or CVM, consists of a 3 or 4-digit numeric code that is printed at the back of the credit card along with (after) the credit card number, where the cardholder signs in his signature on the card.
This additional 3 or 4 digit numeric code is not embossed on the card or available in the magnetic stripe. This additional 3 or 4 digit is code is featured / incorporated on all Master Cards and Visa cards issued worldwide, including cards "Valid only in India and Nepal".
Visa calls this security feature as CVV2 and Master Card calls it as CVC2.
The purpose of CVM is to ensure that the person submitting the transaction is in possession of the actual card, since the code cannot be copied from charge slips / receipts.
Techprocess solutions Ltd requests our customer to provide this numeric code for your order and submits it with the authorization through the SBI gateway.
The card processor (i.e. Visa or Master Card) will then validate the code supplied with the number on record for the specific card, and return a match/no-match response.
