Subsequent Transactions

 
When TransactionIndex is used on subsequent transactions, regular customers do not have to re-supply the card data details however this ONLY works if the merchant developer has made provisions for the following:

• Ability for the merchant to identify the customer, usually by means of user sign-in 
• The merchant has successfully processed a transaction on the customers card at some point in time using the iVeri Gateway 
• That the customer's profile is mapped to the correct Tokenised card details (TransactionIndex, Expiry date etc) returned on the initial or previously processed transaction
  
  

Once the above provisions are made, the merchant developer would be able to display to the cardholder a masked/dotted card number and the expiry date of the card. The cardholder would simply select the masked card on file and make a payment.
