Tokenisation: Transactionindex On Subsequent Transactions

This section explains how to implement a follow up/subsequent transaction using the TransactionIndex returned from an initial/previous transaction processed successfully.
Merchants that wish to accept payments from regular customers without worrying about PCI DSS burdens of storing or retaining the card number have an option of submitting a unique identifier associated with the customers card number from a previously successfully processed transaction. In iVeri's realm, the identifier which the merchant can pass on subsequent transactions is called the “TransactionIndex”. This variable is an iVeri Gateway generated identifier commonly found in Gateway responses to the merchant.
