Verification card mapping notification

Introduction

Verification card mapping notification is initiated through HTTPS POST request by using URLs and the parameters.

Card mapping notification is used to allow Consumer credentials (phone, email, billing address, twitter name, etc) for mapping to card data. Card mappings can be used later in transfer or sale transactions instead of card numbers and other cardholder information. Denumtech sends Verification card mapping notification request to Connecting Party’s server/proxy with created on its side card reference - {serverCardId}.

Connecting Party’s server maps this {serverCardId} to {clientCardId}, created on its side. This {clientCardId} can then be mapped in Connecting Party’s app or on Connecting Party’s server to any Consumer’s data from the initial Perform validation request. This allows Connecting Party’s app to process sale or transfer transactions by Consumer’s email, phone number, etc.

{uniqueReferenceCardId} remains the same if Consumer makes another verification with the same card number but different expiry date, for example. It can be used by Connecting Party for loyalty programs or fraud control.
