Payment Process Flow
Standard Process Flow
In this example, the customer is purchasing an item for £1.00. The Kiosk (Host) initiates the payment system, and the customer is asked to
present their card for payment. The method of payment is determined by the customer, the requirement for the PIN entry is determined by the
card issuer. The card issuer may request the PIN entry on a contactless transaction if the transaction value is high enough. The decision from
the issuing bank will be either Approved (funds available) or Declined (various possible reasons
–
not detailed). Approved will initiate the
issue of the item requested, the funds cleared to the merchant account and the customer’s account will be charged for the pur
chase.
