Settlement is the process of calculating and determining the net financial position of each member for all transactions that are cleared. The actual exchange of funds is a separate process.

Visanet transaction flow
1. The transaction begins when a card is inserted at an ATM or is swiped or keyed at a point-of-sale or point-of-service (POS) terminal. POS and ATM transactions can also be initiated using contactless technology; that is, cardholder data is transferred from the card to the terminal without physical contact. The terminal prompts the cardholder for a personal identification number (PIN), if applicable.
2. The merchant creates a financial request message and forwards
it to the acquirer. The request includes the transaction type, the merchant name, the encrypted PIN, and the transaction amount.
3.The acquirer logs the request, excluding the PIN information, and forwards the message to VisaNet. 4. The V.I.P. System logs the transaction, performs currency conversion if requested, and routes the message to the issuer. Routing is based on the card number and on routing options selected by the acquirer and by the issuer.
5.The issuer verifies the PIN, checks the transaction amount against the accounts available balance or open-to-buy balance, and checks daily activity limits and other controls, if any. The issuer logs the transaction and, for approved transactions, places a hold on the funds or reduces the cardholders available balance by the amount of the transaction. The issuer creates an authorization or financial response message based on the results of these edits and sends it to VisaNet. 6. V.I.P. logs the message and forwards it to the acquirer. 7. The acquirer logs the financial response and forwards it to the merchant to complete the transaction. The acquirer ensures that the response is successfully delivered. If the cardholder did not enter a PIN earlier, the cardholders signature is required.4/23/12
