NS&I has a requirement for the provision of Payment Initiation Services in order to make it easy for our customers to pay NS&I by bank transfer using a secure, simple and efficient process.NS&I Customer research has shown that three key factors influence how customers choose to pay: Security, Ease and Confidence. Payment initiation offers a well-defined journey, with the necessary account details securely transferred using Open Banking technology. This reduces the risk of the customer making an error, and makes it easier for the customer to complete the task than a manually set up bank transfer.For NS&I, Payment Initiation is more cost-effective than debit card. Through the use of Payment Initiation, NS&I aims to reduce our future payment costs.We expect the Supplier to provide Application Programming Interfaces (APIs) to allow NS&I to enable our customers to seamlessly transition from our new mobile app or future website, to the customer's own bank and back to our online service for confirmation.
